Description of problem: The new kernel, 2.6.9-55.0.6.ELsmp panic on boot, unable to find the root partition on sda10. Version-Release number of selected component (if applicable): 2.6.9-55.0.6.ELsmp How reproducible: Every time. Steps to Reproduce: 1. Boot machine. 2. 3. Actual results: Panic after "Red Hat nash version 4.2.1.10 starting" beginning with "mkrootdev: label / not found". Full output attached below. Expected results: "INIT: version 2.85 booting" then normal boot as with 2.6.9-55.0.2.ELsmp and earlier. Additional info: Machine is a Dell XPS M1210 laptop. I'll attach a hand-typed copy of the boot messages before the panic and the output of dmesg from the running 2.6.9-55.0.2.ELsmp kernel. I suspect either that the newer kernel is trying and failing to use SATA drivers and the old is using generic, or the new initrd is missing something (it's ~6k smaller). I'll try making a new initrd and booting from it.

Andrew, could you boot 2.6.9-55.0.6.ELsmp and replace "quiet" with "debug" on the boot line, and then attach the output here? Thanks, P.
Created attachment 193651 [details] last lines of boot with "debug" keyword It occurs to me that another possibility is that mkrootdev is expecting the root partition to have a low number - which it doesn't in this case; / is /dev/sda10 and the partitions are not in disk order. It should find it based on the e2label, but it clearly does not.
Any news on this? Identical problem happens to me on all x86 (not 64 bit) kernels from 2.6.9-55.0.2.ELsmp and beyond. All previous (2.6.9-42.0.8.ELsmp and earlier) boot normally.
If possible, would you please try a more recent kernel? Thank you. http://people.redhat.com/jwilson/el5/204.el5/
Impossible, I'm afraid, the machine's long gone. I got around the bug in the end, but can't remember how, sorry.
Ok, thanks for the info, I will close this BZ, please re-open if necessary.
