Description of problem:
I was testing the patch for BZ#230552
Booting on Altix4 (dual 330) gets into nash but the fails with the message:
Red Hat nash version 18.104.22.168 starting
Unable to find device-mapper major/minor
Reading all physical volumes. This may take a while...
No volume groups found
Volume group "VolGroup00" not found
mount: could not find filesystem '/dev/root'
setuproot: moving /dev failed: No such file or directory
setuproot: error mounting /proc: No such file or directory
setuproot: error mounting /sys: No such file or directory
switchroot: mount failed: No such file or directory
Kernel panic - not syncing: Attempted to kill init!
Version-Release number of selected component (if applicable):
both times tried
Steps to Reproduce:
1. Boot to RHEL5
2. Patch rawhide kernel and install
3. Boot rawhide kernel w/ patch
Best guess offhand is that this has to do with the big libata overhaul. Quite a
few systems are failing to boot recent rawhide kernels, especially if scsi disks
are involved, because the driver/drives aren't ready yet by the time we try to
access them. Previously, the old ata code introduced enough latency in the
module load process, that the drives were up by the time we tried prodding them.
(See bug #220470 for reference). As detailed there, you may be able to add a
5-10 second delay in the init script in your initrd to get things working...
How's this looking with the current tree ?
