Description claire robinson 2014-01-22 08:05:58 CET
Initially noticed with 4RC Live ISOs, much slower than Classic ISOs

They load very slowly, using USB 1 seemingly rather than USB 2. The kernel loads at roughly 1% per second.

lspcidrake attached

I'll attach one later from mga4, in case they are different.

lewis has also been reporting slow live isos so adding him in CC

lewis could you attach the lspcidrake.txt from

lspcidrake -v > lspcidrake.txt

Thanks

Would oblige if I could, but it is water under the bridge now. I currently only 'live' install 64-bit from USB stick, and do not recall anything excessive lately. If I complained, it was probably re 32-bit Gnome Live DVD from actual DVD; but the issue was clouded by doubtful ISOs. I do not do that any more, as the installed result was unuseable on the box in question. Sorry.

kernel loading slowness really is BIOS slowness...

I have updated the bios (to a 2010 one) since the betas which I am inclined to blame. It's an order of magnitude slower loading live isos than classic isos though.

dmesg.txt from live session kde livecd

I'll download mga3 livecd, or maybe even mint/ubuntu and try those next.

If theyre similar then it's obviously a bios regression and not a mageia regression.
Comment 8 Thomas Backlund 2014-01-24 10:58:13 CET
ok, so it sees a lot as usb1. and I see some ubuntu and fedora users have seen the same.


is bios usb options set to run ports at usb2 speed ?

check that the ports are configured for "hi speed" and not "full speed" or "low speed"

the first one is 480Mbit, the second 12Mbit, and the third 1,5Mbit

lsusb -t will report current speed it runs at.


if none of the above helps, try to boot with: rd.blacklist=uhci-hcd

fedjournal.txt from a fedora 20 live iso

Mga3 livecd was similar, I double checked bios settings and there are just enable/disable usb and enable/disable legacy usb with no speed settings.

Attached is the journal taken from live session of a fedora 20 iso
(which, incidentally, booted to a US locale)

I also grabbed dmesg there.

I'll try again with rc.blacklist but unless anything shows up here we should probably write it off as a bad bios.

rd.blacklist=uhci.hcd doesn't seem to make a difference. I'm happy if you want to close this as a bios regression
Comment 12 claire robinson 2014-01-24 13:33:24 CET
uhci-hcd i mean
Comment 13 Lewis Smith 2014-01-24 13:48:00 CET
If it helps...
Just tried & installed both 64-bit Gnome & KDE Live DVDs Final 2nd round from USB stick. Live, both reached 1st (language) dialogue in ~2m, and went from the last (keyboard) to visible desktop in ~1m. Is this normal or excessive? I think normal.
Comment 14 claire robinson 2014-01-27 11:13:25 CET
closing as a bios issue

Status: NEW => RESOLVED
Resolution: (none) => FIXED
