Description Peter Wallace 2012-04-21 18:12:13 CEST

Fresh install of Mageia 2 beta 3 64bit of a pen drive via mandriva seed.

After installation the dvd drives are not working.

Drives are on the primary IDE channel
they shown as on /dev/hda and /dev/hdb.

I believe it is related to this bug here:-
https://bugs.mageia.org/show_bug.cgi?id=4997

Here's the output of the various commands of my setup.

alias eth0 r8169
alias sound-slot-0 snd_hda_intel

Now I think its the fact it is placing the drives in group disk instead of cdrom.
Have tried rdloaddriver=pata_amd with no luck.

Steps to Reproduce.

1 Install then reboot.

Comment 2 Colin Guthrie 2012-04-22 13:16:26 CEST

What about rdloaddriver=pata_jmicron seeing as that's what driver seems to be used for your device.

Check that this driver IS actually in your initrd first by doing:
lsinitrd | grep jmicron

Comment 3 Filip Komar 2012-04-22 13:26:04 CEST

In my opinion this is duplicate of bug 4997.

Did you try workaround from bug 4997, comment 11?

That did it, never tried that as was loaded in modprobe.conf. 
Guess it needs it at initial boot time as to sort out the drive arrangement.

Comment 5 Colin Guthrie 2012-04-22 14:19:17 CEST

Incidentally, how was it done in modprobe.conf?

Was it via ide-controller? Can you paste the text that should do it?

Comment 6 Colin Guthrie 2012-04-22 14:38:30 CEST

Also, out of curiosity, if it is via the ide-controller thing in modprobe, does adding rdloadmodule=ide-controller work?

Comment 7 Colin Guthrie 2012-04-22 14:39:04 CEST

Sorry, I mean rdloaddriver

Comment 8 Colin Guthrie 2012-04-22 14:45:01 CEST

Actually, never mind about the rdloadmodule=ide-controller test, but I'd still be interested in your modprobe.conf line that should do this for you.

Comment 9 Peter Wallace 2012-04-22 15:17:39 CEST

My modprobe.conf output.

install scsi_hostadapter /sbin/modprobe mpt2sas; /sbin/modprobe ahci; /sbin/modprobe ata_piix; /sbin/modprobe pata_jmicron; /bin/true
install usb-interface /sbin/modprobe ehci_hcd; /sbin/modprobe ohci_hcd; /sbin/modprobe uhci_hcd; /sbin/modprobe xhci_hcd; /bin/true
alias sound-slot-1 snd_hda_intel
alias eth0 r8169
alias sound-slot-0 snd_hda_intel

It does state pata_jmicron. but it only worked when I added it at boot time.

Also if I do lsmod | grep ata it states pata_jmicron isnt been used. as shown on the initial report. 

but what is missing now out of lsmod is ide_cd_mod, ide_pci_generic, ide_core.

Could it have been a conflict between modules?

Comment 10 Peter Wallace 2012-04-22 15:24:00 CEST

For got to add the out put of lsinitrd | grep jmicron

lsinitrd | grep jmicron

Well I believe that when done this way (via the pata_jmicron module) that the ide specific module are no longer needed as everything is going through the ATA layer. Assuming that everything does indeed work, then I wouldn't worry too much about those modules being missing.

We just need to find a way to actually load the module by default....
