Description of problem: panic on boot as udev starts after kernel 2.6.19-2895fc6 update Version-Release number of selected component (if applicable): 2.6.19-1.2895.fc6 and 2.6.19-1.2895.fc6debug How reproducible: Always Steps to Reproduce: 1. Boot the 2.6.19-1.2895.fc6 kernel. Previous kernel (2.6.18-1.2868.fc6) boots fine. Actual results: Kernel panic, apparantly as udev loads. Expected results: clean boot. Additional info: Machine is a dual core Satellite M115-S3094 laptop. Since the panic happens before syslog starts, nothing is logged and I only see the final screen of the panic. It appears to be triggered by udev loading some module but I can't be sure. I'd be glad of advice how to better debug this. The 2.6.19-1.2895.fc6debug kernel gives the same result.
Take a picture of the screen using a digital camera and post that as an attachment. (Try to cut down on the picture resolution if you can -- we don't need to see every speck of dust on the screen.)
I have the same problem on dual emt64 IBM blades...I'm not sure about udev though.. I my case initrd seems unable to find/mount lvm root partition... It also can not see /dev/lovgroup/swap. Is there a grub/initrd option to execute /linuxrc step by step, so I can pinpoint the problem? I'm using remote control on my blades and console output runs away from me...Then I can post it here...
You may want to take a look at bug 224283. This is exactly the same problem that I'm having and I'm also using a Toshiba M115 laptop but the S3144 model. I was able to find a work around to get it to boot, which is really only useful for gathering log files I don't think that you would want to try and do anything with the system in that state. From what I have been able to gather, and this is just a swag on my part, it seems that the crash occurs while trying to initilize the sound system (alsa). I've seen a comment on one of the mailing list that indicated some have had success with creating and installing the alsa 1.0.14 rc2 kernel drivers. But I've had no success in creating an rpm of that driver yet.
Indeed the same bug as on my wife's M115-S3094 laptop. I've marked this as a duplicate of <a href="https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=224289"> bug 224283</a> *** This bug has been marked as a duplicate of 224283 ***
I'm not sure if my problem is the same is yours...I have a prob with servers and there is no sound card there...In my case system can't find/mount a root partition... I'd say it has to do with lvm2...my root partition is in the logical volume... Just found something that looks like mine: https://fcp.surfsite.org/modules/newbb/viewtopic.php? topic_id=32786&forum=11&post_id=144762#forumpost144762
I've fixed my problem by recompiling initrd: mv initrd-2.6.19-1.2895.fc6.img initrd-2.6.19-1.2895.fc6.img.orig mkinitrd --force-lvm-probe --with=ext3 /boot/initrd-2.6.19-1.2895.fc6.img 2.6.19-1.2895.fc6 But i'm sure it won't fix yours... Try to yum update again, I've noticed new sound modules and a new deviceMapper in the updates
I'd like to thank the author of the comment #6. His approach solved my problem. Here is the report: the root partition is on a a LV created on a software RAID1 array built from 2 SATA disks on Intel Celeron D desktop system with Intel 945 chipset. The 2.6.18 kernel is fine, but 2.6.19 doesn't boot. The screenshot follows.

I reviewed the change log for 2.6.19-1.2911 and didn't see anything that would lead me to believe it would resolve the issues that I'm having but updated anyway and gave it a try. Results are that the crash detecting the sound device is fixed, no crash on start up. However sound still does not work and something that I noticed with the previous kernel, eth0 seems to load fine but it will not function. I continue to get 'no link present check cable'. Even though it is connected, wireless does work however (using dkms-ipw3945 driver from freshrpms). I haven't gone back and tried the r1000 driver (from Realtek site) as that did not work in the previous kernel (2.6.19-1.2895) but eth0 with the r1000 driver does work in the last 2.6.18 kernel. In any case there does seem to be some progress, thanks to all! I've also attached two files generated by the sound configuration tool. If there is anything further that I might provide let me know and I'll try to accomodate.
Same results for me as in comment 11. But these comments should not be posted here -- this bug is marked closed, duplicate of bug 224283.
