If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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.

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".
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.
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!
Closing as duplicate of the ALSA HDA update for 6.3. It seems that all issues are solved in the 6.3 kernel.

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.
