kernel panic: Unable to boot after changing scsi controller & switched to other hardware

[Schlueri]

Hi,

i want move a installed fedora core 1 to a new machine.

The system is installed on two scsi drives configured as raid 1.

/dev/md0 -> /dev/sda1 & /dev/sdb1 -> /
/dev/md1 -> /dev/sda2 & /dev/sdb2 -> /boot
/dev/md2 -> /dev/sda5 & /dev/sdb5 -> /home

On the old machine the scsi module sym53c8xx is used, the new machine
needs aic7xxx.

I've changed /etc/modules.conf and /etc/modprobe.conf:
alias scsi_hostadapter sym53c8xx -> alias scsi_hostadapter aic7xxx

and rebuild initrd with:
mkinitrd -f -v /boot/initrd-2.4.22-1.2199.nptl.img 2.4.22-1.2199.nptl

i tried also with:
mkinitrd -f -v --preload=aic7xxx /boot/initrd-2.4.22-1.2199.nptl.img
2.4.22-1.2199.nptl

On the new machine the system boots, the kernel find the adaptec
controller and the 2 Harddisks. Then i get a kernel panic and message:

isofs_read_super: bread failed, dev=09:01, iso_blknum16, block 32
Kernel panic: VFS: Unable to mount root fs on 09:01

If i boot the new machine with the fc1 cd in rescue mode, anaconda loads
aic7xxx and mounts my raid without problems.

Have i missed something?

Thanx for help!
