SubjectMonthly md check == hung machine; how do I debug?
I've got a machine with a 4 disk SATA raid10 configuration using md.
The entire disk is loop-AES encrypted, but that shouldn't matter
here.

Once a month, Debian runs:

    /usr/share/mdadm/checkarray --cron --all --quiet

and the machine hangs within 30 minutes of that starting.

It seems that I can avoid the hang by not having "mdadm --monitor"
running, but I'm not certain if that's the case or if I've just been
lucky this go-round.

I'm on kernel 2.6.23.1, my own compile thereof, x86_64, AMD
Athlon(tm) 64 Processor 3700+.

I've looked through all the 2.6.23 and 2.6.24 Changelogs, and I
can't find anything that looks relevant.

So, how can I (help you all) debug this?

-Robin
