I've got a x86_64 system with 2 3ware 9550SX-12s, each set up as a raid5
w/ a hot spare. Over that, I do a software raid0 stripe via:
mdadm -C /dev/md0 -c 512 -l 0 -n 2 /dev/sd[bc]1
Whenever I try to format md0 (I've tried both mke2fs and mkfs.xfs), the
system OOPSes. I'm running centos-4 with the default kernel, but I've
upgraded the 3ware driver/firmware to the most recent versions. Based on
the OOPS I'll paste below, who should I be blaming for this crash? Any
ideas on how to fix it? Thanks.
