Description Elliot Lee 2002-03-07 23:12:06 UTC 
See attached raidtab and ksymoops report.

I know this appears odd, but I need nested one-device RAID array for testing
purposes, and the kernel just shouldn't oops like this.

kernel is 2.4.9-24

Comment 3 Elliot Lee 2002-03-07 23:14:50 UTC 
To reproduce, copy the raidtab in place (and modify for local system as needed),
then do:

  mkraid /dev/md0
  mkraid /dev/md1
Comment 4 Arjan van de Ven 2002-03-08 14:25:51 UTC 
Hmm it seems the kernel doesn't like a raid1 of only 1 disk
which architecture is this btw ?
Comment 5 Elliot Lee 2002-03-08 15:30:12 UTC 
It's not a RAID1 of one disk (which seems to work), but a RAID1 of one RAID1 -
the oops only happens after you do the second mkraid.

alpha arch.
