raid1 rootfs: 2.6.3 kernels panic at boot on Proliant DL360 P21
Last modified: 2007-11-30 17:10:38 EST
Description of problem:
Started with FC1, not 1.90. And the 2.4 kernels still boot fine. But
2.6 kernels I have added fail to boot. pci=noacpi and acpi=off help it
get further so it successfully recognizes and binds partitions to the
raid1 devices, but it fails to mount the ext3 root filesystem
contained within. That causes pivot_root to fail, and init to not be
found, resulting in a panic. Boot messages captured on a serial
console are attached.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot 2.6.3 i686 kernel from rawhide rpms on DL360 P21
Actual Results: Kernel panic
Expected Results: Normal boot like 2.4 kernels do.
This is 1GHz P4 processor with two SCSI drives, all partitions (except
swap) mirrored across the drives using software raid 1. The hardware
raid controller board has been removed from the SCSI controller, thus
is not a factor.
The P21 BIOS has been flashed to 11/15/2002 (the latest).

Serial console capture of 2.6 kernel boot process including panic
I upgraded mkinitrd and modutils packages from rawhide and installed
packages device-mapper and lvm2 to resolve dependencies.
Then I made a new initrd and rebooted. Using FC1's mkinitrd and/or
modutils was the cause of the 2.6 boot problem.
