Thanks for this detailed bug report.

Apparently, that naughty mailing list software apparently has dared to cut out
the "how to reproduce" section, as well as all the other relevant information,
notably exact kernel revision, relevant kernel config settings, compiler used,
the RAID / md configuration involved etc, all of which you certainly provided.

Before I even configured it, this showed up.
How is that relevant?
I compiled the options into the kernel, rebooted, it is at this point
when I get the problem.

How is your RAID configured?

Because you did not mention it before at all. There was no way of knowing
whether you used a special RAID configuration which triggered the problem.

In any case, I cannot reproduce it. Maybe you should try the latest .21pre
kernel instead, perhaps its doing better for you?
