From: Kermit on
I'm trying to upgrade from 2.6.18 to 2.6.22 (on RHEL).

My root partition is on an logical volume on a SCSI disk, and this seems to
be causing some problems:


Uncompressing Linux ... Ok, booting the kernel.
Red Hat nash version 5.1.19.6 starting
SCSI 0:0:0:0: timing out command, waiting 24s
SCSI 0:0:0:0: timing out command, waiting 24s
SCSI 0:0:0:0: timing out command, waiting 24s
Reading all physical volumes. This may take a while...
No volume groups found
Volume group "VolGroup00" not found
Unable to access resume device (/dev/VolGroup/00/LogVol01)
mount: could not find filesystem '/dev/root'

As far as I can see, I've compiled in all the SCSI/RAID/LVM code (mostly as
modules), and have compared my configuration with that of the working
2.6.18 kernel, so I'm a bit lost.

Would these errors indicate that the required SCSI driver wasn't found
(hence the SCSI disks could be searched for a volume)?

This is what I see when I boot with a working kernel:
