hi, this is very reproduceable: boot, raidstart, ctrl+alt+del, BOOM! 2.2.13 with Ingo's raid patch, booted from initrd, very small kernel. the only special thing is the raid0 are hda & hdc (no partition). i have other setups using partitions which work well. another problem: a machine running raid5 (from the same kernel tree from above) from 4 nbd and a raid0 (sda + hda) lock hard. mkraid runs, but writing to the raid5 has put raid5syncd into D state. tia for any help. posted on lk but no response, please cc me, i'm not on linux-raid. imel
