Tejun,
   Looks like I had a failure today. First one in weeks and only the
3rd or 4th boot with this newer patch file. One of the two drives
making a RAID0 wasn't found so /dev/md11 (constructed from /dev/sdd
and /dev/sde) couldn't be started. I did a cold reboot and the drive
was found.

   If it matters, and it probably doesn't, the failure came on a boot
which had a scheduled fsck to do of /dev/md5 - my main / drive. I
don't see how that would make a difference but I figure why leave the
info out. That's why the times are so much larger in the dmesg file.
(I think)

   dmesg attached. I patched the Gentoo kernel if it makes a
difference, same as I did with the earlier patch.
