RE: FC3: kernel panic on first boot



Having same problem with SCSI drives.  It is because the bootable SMP kernel builds do NOT contain the ext3 drivers by default.  Serious build mistake.

Subject: FC3: kernel panic on first boot


Hi,

First some system details:

Epox EP-D3VA motherboard
dual 1Ghz PIII processors
1.5GB RAM
2 x Promise SATA150 TX4 controllers
6 x Maxtor Maxline II 250GB SATA HDDs (3 per controller)

The drives are all partitioned identically with two partitions: 1.5GB + 
248.5GB. The partitions are configured in raid arrays as follows:

/dev/md0: /dev/sd[ad]1		/ (root filesystem)
/dev/md1: /dev/sd[be]1		swap
/dev/md2: /dev/sd[cf]1		swap
/dev/md5: /dev/sd[abcdef]2	lvm2 volume

/home, /usr, and /var are mounted as lvm2 logical volumnes on the 
/dev/md5 array.

I was running FC2. I then decided to upgrade to FC3.

I booted from the DVD (the media check completed OK) and went through 
the system upgrade.

All seemed to go well and I rebooted.

However, the boot process halted with the following message:

Loading ext3.ko module
md: Autodetecting RAID arrays.
md: autorun ...
md: ... autorun DONE.
md: Autodetecting RAID arrays.
md: autorun ...
md: ... autorun DONE.
md: Autodetecting RAID arrays.

mount: error 22 mounting ext3
mount: error 2 mounting none
Switching to new root
switchroot: mount failed: 22
umount /initrd/dev failed: 2
Kernel panic - not syncing: Attempted to kill init!

This is with the default 2.6.9-1.667smp kernel.

I booted into rescue mode and chrooted into the upgraded system - all
seems fine, i.e. all the filesystems are OK.

I then upgraded all the packages using "yum upgrade" within the chroot
environment. This installed kernel-2.6.9-1.681_FC3smp.

I rebooted and got the same error as above. I also tried "downgrading" 
to a 2.6.8 kernel but got the same error.

Am I hitting the known bug [1] with SATA drives in the 2.6.9 kernel ? Or 
is this some other problem?

Can anyone shed any light on this problem?

Thanks,

R.
