Waiting for device /dev/900 to appear

OK, id did a complete new installation (same box) with the same disk-configuration: /dev/hda2 + /dev/hdb2 als raid1: /dev/md0 = / #root (ext3) /dev/hda1 = /boot from original CD SuSe 91prof. minimal System installed. all works fine until i upgrade the kernel 2.6.4 to 2.6.5 from the ftp.suse.com with YOU. The boot aborts with: raidautorun ... waiting for device /dev/900 to appear ...(short delay ) .... not found.... RAIDs never saved me from a "dilemma", for me, the always created one !
