It's the whole array that is missing. The raid-1 arrays appear but the
raid-0 does not.

Attaching two boot logs for 2.6.37.3 with /dev/md6 missing, and one for
2.6.37.2.
Note that md1, md2, and md3 have v0.90 superblocks, whereas md5 and md6 have
v1.20 ones and are assembled later.
When /dev/md6 is successfully assembled, through the gentoo init scripts
calling "mdadm -As", the log contains:
messages.2:Mar 8 20:44:19 xi kernel: md: bind<sda6>
messages.2:Mar 8 20:44:19 xi kernel: md: bind<sda5>
messages.2:Mar 8 20:44:19 xi kernel: md: bind<sdb5>
messages.2:Mar 8 20:44:19 xi kernel: md: bind<sdb6>
and when it fails, either the sda6 or sdb6 bind is missing:
messages.3-1:Mar 8 20:04:39 xi kernel: md: bind<sda6>
messages.3-1:Mar 8 20:04:39 xi kernel: md: bind<sdb5>
messages.3-1:Mar 8 20:04:39 xi kernel: md: bind<sda5>

I mentioned that something similar had happened before, but that a
reboot fixed it. Tonight I cannot seem to be able to reproduce the
issue, so it's could very well be that the problem lies elsewhere and
that only slightly changed timings or such made it appear three times in
a row in the three first 2.6.37.3 boots (with 2.6.37.2 working in
between)...
Thanks,
Johan
