Created attachment 549576 [details] photo of the panic backtrace Description of problem: After upgrading an Asus eeepc 1005PE to the 2.6.32-220 kernel (from the 2.6.32-131.21.1 kernel), I reliably get a panic at boot after dracut switched root and udev starts up. This also happens with a 2.6.32-220.2.1 kernel. I'll attach screenshots what I could grab of the panic. # cat /proc/asound/card0/codec* |grep Codec Codec: Realtek ALC269
Created attachment 549577 [details] different backtrace
Forgot to mention that if I pick the older 2.6.32-131.21.1 kernel in grub, the boot is successful
Probably related is the fact that after installing the 2.6.32-220 kernel on a system with a ALC887 8-Channel High-Definition audio controller there was no sound output anymore (hardware was recognised correctly). Reverting back to the 2.6.32-131 kernel made the sound come back. In order to get sound working while using the 2.6.32-220 kernel I had to create /etc/modprobe.conf and add "options snd-hda-intel model=generic".
a similar issue has been reported at: http://bugs.centos.org/view.php?id=5368
Please, test the kernel hda632 from: http://people.redhat.com/~jkysela/RHEL6/ Install it using 'rpm -ivh <rpm>' on the command line.
I installed the kernel and commented out the line "options snd-hda-intel model=generic" from /etc/modprobe.conf. There was no kernel panic and the sound is working.
is this fixed in 5.8 GA? I don't see anything about this bugzilla number in the changelog... Thanks
oops my bad, just discard my previous comment, fever and bug report on friday afternoon is a cocktail for failure!
-> missing kernel-firmware: [tru@snoopy-c6 ~]$ sudo rpm -ivh kernel-2.6.32-228.el6.hda632.i686.rpm error: Failed dependencies: kernel-firmware >= 2.6.32-228.el6.hda632 is needed by kernel-2.6.32-228.el6.hda632.i686 as of today I only see: [ ] kernel-firmware-2.6.32-228.el6.dpo631.noarch.rpm 09-Feb-2012 11:51 6.3M RPM package file [ ] kernel-firmware-2.6.32-228.el6.oss632.noarch.rpm 09-Feb-2012 05:05 6.3M RPM package file
Use 'rpm -ivh --nodeps <rpm>'.
I tried the test kernel at: http://people.redhat.com/~jkysela/RHEL6/ and I find that it DOES resolve the problem reported here: http://bugs.centos.org/view.php?id=5368 when run on my eeepc 901.
I'm seeing the same thing on my Asus Eee PC 1008HA... - 2.6.31-131* = works great. - 2.6.32-220* = panics right after udev starts. - 2.6.32-220* + /etc/modprobe.conf with "options snd-hda-intel model=generic" as noted in Comment 4 = no panic, but sound does *not* work (unlike the findings in Comment 4 and Comment 8). - 2.6.32-228.el6.hda632 = no panic and sound works great!
For my EEE 1008 it also fixes the Audio isue. 2.6.32-228.el6.hda632 is the solution for me. Thanks.
Took me a while to test, but 2.6.32-228.el6.hda632 is also working fine for me.
Closing as duplicate of the ALSA HDA update for 6.3. It seems that all issues are solved in the 6.3 kernel. *** This bug has been marked as a duplicate of bug 760490 ***
i seem to have the 2.6.32-279 kernel. I still have the issue of a reboot when udev is starting just not everytime. Disabling the HDA device did not work either, so I suspect it is something else. Should the mentioned kernel have the fix applied? I thought I enabled crash dumps, buth found nothing in /etc/crash.
update: I mean /var/crash I have a Asus V7P7H55E . Guess I'll try that kernel too
no solution for me. I found it is a APIC problem. Darn crappy Asus bios. That is my last Asus PC purchase
