I recompiled kernel 2.4.21-xfs to include raid0 and md modules, I installed lilo, after reboot I obtain this error:

/modules/reiserfs.o: kernel module version mismatch
/modules/reiserfs.o was compiled for kernel version 2.4.21-xfs
while this kernel is version 2.4.21
FAT: bogous logical sector size 0
FAT: bogous logical sector size 0
md: swapper(pid 1) used obsolete MD ioctl, upgrade your software to use new ictls
kernel panic: VFS: Unable to mount root fs on 09:00

The system has 2 hard disks with 3 partitions with raid 0 fs:reiserfs, swap partitions and a ext3 /boot non-raid partition
I recompiled source of knoppix 2.4.21-xfs kernel not 2.4.21 vanilla version, then I don't understand the error.

Please help me to boot the system.

Thanks.
