Kernel panic f7t3 and f7t4

[Andy Baumhauer]

I'll assume that you already know that /dev/hdX drives now appear as 
/dev/sdX devices.  Based on your post, your boot is failing before any 
of this would even matter.

I believe your problem is that the md raid driver is not being loaded by 
initrd during boot initialization.  I had the same problem (see my 
posts, and bug entitled Kernel panic: LVM not working in kernel since 
2.6.20-1.3069 on this list) with Logical Volume Manager.

My problem was that all of my /etc/fstab entries were using LABEL= or 
UUID= to describe disk partitions.  When installing the kernel, the 
mkinitrd script builds the initrd in /boot for the kernel.  It is full 
of conditional code (it's a bash script that writes a nash script).  I 
suspect that the mkinitrd script can't determine that you are running 
meta disks, and the appropriate initialization isn't occurring.

I debugged my problem by:

cd /tmp
cp /boot/initrd-<kernel release version>.img /tmp/initrd-<kernel release 
version>.img.gz
gunzip initrd-<kernel release version>.gz
mkdir initrd
cd initrd
cpio -cid -I ../initrd-<kernel release version>.img

now examine the init nash script against a working script (from CentOS).

My bug is https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=237415

The module to file against is most likely mkinitrd, if the problem I had 
is causing your problem.

I hope that this points you in the right direction.
