[nmglug] raid1 kernel crash

[js at jasonschaefer.com]

My OS is Debian 3.1r0a. I can boot into hda without raid. I can build
the raid with mdrun, currently it is still missing hda. I want it to
boot before adding hda to the raid.

fstab:
proc            /proc               proc    defaults        0       0
/dev/md0       /                    ext3    defaults,errors=remount-ro
0       1
/dev/md2       /home           ext3    defaults         0       2
/dev/md1       /var               ext3    defaults         0       2
/dev/hda1       none            swap    sw,pri=1      0       0
/dev/hdb1       none            swap    sw,pri=1      0       0

menu.lst:
