Description Dick Gevers 2014-11-30 19:32:38 CET
Description of problem:

Today's new kernel-server was installed and on reboot (2x) I found resposiveness much too slow for comfort, decidedly less so than all other recent kernels.

Moreover I was not able to switch to a tty1 with [ alt + ctrl + function key ].

After booting up the copying of a huge file to another file is timed to take 5+ seconds. After restarting dbus service it still takes 0.8+ seconds. (I did this restart suspecting the dbus bug recently being discussed which I did not suffer).

Nevertheless the apparent unresponsiveness (to back completion, scrolling through the htop process listing, etcetera) did not go away by that restart, nor by a further reboot to the same kernel.

Subsequently I rebooted to the previous kernel still installed: kernel-server-3.17.4-1.mga5 and find that responsiveness is fine again, plus I can change to a tty.

I shall attach some files to show the situation I'm talking about.

Reproducible:

journalctl -a of new kernel install and (after reboot) use

With the same kernel, on this system:

https://wiki.mageia.org/en/User:Marja/QA/Hardware#Lenovo_ThinkPad_L530
(But without the Ralink USB Wlan adapter, seeing it in the old lspcidrake -v output makes me suddenly remember I needed that one for two different access points on - only - this laptop, until I switched to NetworkManager)

I could switch to a text tty without problems, and the system didn't seem slow. The only problem was WLAN connection, which worked, but worked badly: watching a television stream worked near to not at all. Typing in my irssi session on my raspberry went almost as bad as if I was on a 3g network instead of on the same local network as the raspberry.

Rebooting with the previous kernel made the problems disappear.

I'll attach 
journalctl -a --since="2014-11-30 15:08:54" --until="2014-11-30 17:37:00" 2>&1 | tee kernel_3.18.0-0.rc6_journalctl-a from the moment I installed the new kernel, then some (re)boots using it until I finally gave up.

If this is unrelated to dvg's problem, then I'll clone this bug for whatever my issue with this kernel is. Just tell me :-)

rc7.1 is perceived to be a little less slow, but still it is too slow for comfort.

Same here wrt the network problem. There might be a little improvement, but it is very far from good enough.
Comment 10 Marja Van Waes 2014-12-05 15:16:42 CET
Hmm, I had missed that dvg was talking about kernel-server (I should better read the summary)
I was talking about the desktop one.

After the KDE updates, I accidentally booted into kernel-desktop-3.18.0-0.rc7.1 and did no longer see much of the problems I reported before. So whatever caused my bad network connection with that kernel, it is unlikely it was the new kernel itself.

@Dick: can you test if kernel-desktop behaves the same or not

And preferably with 3.18.0 final wich is currently building
Comment 14 Dick Gevers 2014-12-08 11:24:43 CET
I will try latest server and desktop as soon as I see them
Comment 15 Dick Gevers 2014-12-08 12:40:23 CET
I perceive some improvement, equally with desktop and kernel in 18-0.1 and tty's can now be accessed again. So yes, better.

But I still prefer the last 17: kernel-server-3.17.4-1 which is decidedly faster for me. 

I agree that 18-0.1 is getting closer to 17.4-1 in respect of speed (responsiveness), but I do notice still a marked difference.

Comment 16 Marja Van Waes 2014-12-11 11:57:44 CET
_Probably_totally_off_topic_

Sorry, but I don't have a clue against what to report:

The network issues I reported before still exist, after all, but now with the 3.17.4 kernel, too. A 5beta1 install (only tested with the new kernel!) has it, too.

On the first install, with NetworkManager, a second WLAN adapter won't work at all (forgot to check whether there is still an old line in a congfiguration file about disabling NM for it that didn't get overwritten when I re-added the adapter)

On the second install, without NetworkManager, the second WLAN adapter has the same problems as the first (so video streams don't come in smoothly and there are delays even with just ssh'ing into an irssi session on a local network server and typing a message).


Yesterday, after starting "mcc" on a remote Mga4 system I had ssh'ed into, my system here almost froze. That was with the new kernel, I hope to find time to try again with the 3.17.4 one.

Is it possible that a hardware issue outside the WLAN adapters causes problems with both?

Or maybe I should first try a nonfree 5beta1 install with nonfree drivers, but without updates?
Comment 17 Marja Van Waes 2014-12-11 14:49:50 CET
I do see very many lines of this now, on the first cauldron I had problems with after updating to a 3.18 kernel:

Comment 21 Marja Van Waes 2014-12-13 22:39:40 CET
I do *not* have this problem on another laptop with intel wifi card.


The one with the problem, has the same issue with the 2nd round pre-5beta2 KDE Live DVD

journalctl -f did hung and had to be restarted to show the related errors.

Whiteboard: (none) => 5beta2

Comment 22 Marja Van Waes 2014-12-13 23:13:18 CET
however, on the same laptop, a Ralink 802.11 n WLAN adapter
( rt2800usb  : Ralink|802.11 n WLAN (vendor:7392 device:7711) )
won't work at all with the 3.18.0 desktop kernel, but it works fine with the 3.17.4 desktop kernel.

with 3.18.0 I saw this:

dec 13 22:51:49 localhost kernel: ieee80211 phy1: rt2x00usb_vendor_request: Error - Vendor Request 0x06 failed for offset 0x0404 with error -71

dec 13 22:51:49 localhost kernel: ieee80211 phy1: rt2800usb_set_device_state: Error - Device failed to enter state 4 (-5)
Comment 23 Marja Van Waes 2014-12-13 23:33:08 CET
The above errors for the Ralink were with the KDE Live DVD

On an existing cauldron install (the same one where that WLAN adapter works fine with the old kernel), I see an avalanche of:
Dec 13 23:29:08 DenkBlok3Cauldron5a1_EFI NetworkManager[834]: <error> [1418509748.883984] [supplicant-manager/nm-supplicant-interface.c:856] interface_add_cb(): (wlp0s20u2): error adding interface: wpa_supplicant couldn't grab this interface.

The wlp0s20u2 is the Ralink

Latest today, regret I have to say as earlier:

I perceive some improvement with 18-0.2. So yes, better.

But I still prefer the last 17: kernel-server-3.17.4-1 which is decidedly faster for me. 

I agree that 18-0.2 is getting closer to 17.4-1 in respect of speed (responsiveness), but I do notice still a marked difference.

Didn't log out, but plugged in the USB wlan adapter that wouldn't work with this kernel before, so this one:
rt2800usb       : Ralink|802.11 n WLAN (vendor:7392 device:7711)
and disabled the on board one.

At first it worked, but not very well, it resembled the Realtek one.

I didn't catch a repeating error when it still worked.

After that, there came the following error, endlessly repeated, and I had no more connection:

That actually makes me happy, as I can keep the new improved block scheduler active :)

As for your problem, it might be the mm bug that is still being tracked / figured out...

This is really a different bug that could have had it's own bugreport, but no need for now as I now have found the fix for it.... Seems upstream forgot some more fixes during fw management conversion...

I will merge the fix now so it will be part of next kernel build

for the Realtek, it works lots better, even after ssh'ing from a remote network into my irssi session I don't see any delays when typing messages, the "Fw download fail!!!" error is gone and surfing the internet works fine.

Forget about the Ralink!

Using the new kernel doesn't work too well with the WAP where I am now, *but*:
this time, after rebooting into the _3.17_ kernel, and disabling the on board card, there is no wlan at all.

[marja@DenkBlok3Cauldron5a1_EFI BlueHD]$ uname -r
3.17.4-desktop-1.mga5
[marja@DenkBlok3Cauldron5a1_EFI BlueHD]$

And in journalctl -f and endless amount of:

Anyway, I'm glad the on board WLAN adapter card works well, now :-)

Just to be sure, I used the new kernel for several hours today. But it is not really bearable. If this were the standard now I would say: it is time to buy a new computer. Except now I know it does work well with kernel-server-3.17.4-1.

@Dick

Can you add dmesg from 3.19 too so I can see if it behaves any differently
Comment 49 Dick Gevers 2015-02-23 18:26:30 CET
Created attachment 5941 [details]
dmesg of kernel-server-3.19.0-2

Sure. Attached.

@Dick

Do you still have issues with 
tty1 with [ alt + ctrl + function key ]
on kernel 3.19.0-4 ?

Do you have an nVIDIA graphics card?

On my notebook with nVIDIA GeForce GT650M and Mageia 5 beta 3 with kernel 3.19.0-desktop-4 I get a black screen when pressing CTRL-ALT-F2. But when I type it actually works, but it is not visible. CTRL-ALT-F1 goes back to KDE.

CONFIG_X86_SYSFB=y
http://gentoo-en.vfose.ru/wiki/UEFI#Kernel_Options
Would setting this kernel config flag be a solution for the tty issue ?
Comment 55 Dick Gevers 2015-03-04 16:13:43 CET
Applies to latest kernel. 

To: bert.ram.aerts@gmail.com per #c52: the other tty's can be reached okay here, no problem.

Tried it for a few days, and there is surely improvement since this was first reported, but it is still not as good an instant response as with kernel 3.17.4-1.mga5

With 3.19.2-2 I am happy it is as good as 3.17*.

Thank you!
