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! Dirk
