Thanks for the quick feedback.  Please send a summary of symptoms to
linux-raid@vger.kernel.org, cc-ing Neil Brown <neilb@suse.de> and
either me or this bug log so we can track it.

Be sure to mention:

 - steps to reproduce, expected result, actual result, and how
   the difference indicates a bug (should be simple enough ---
   the summary you sent here would work fine)

 - which kernel versions you have tested and what happened with
   each

 - full "dmesg" output from booting and reproducing the bug, as
   an attachment

 - any other weird symptoms or observations

 - what you would be able to do to track it down (can you run commands
   if provided? try patches? bisect to find which commit introduced
   the regression?)

If we're lucky, the symptoms will ring a bell for Neil or someone else
on-list or someone will have an idea for a test to try to track it
down further.  Otherwise, the best we can do is probably to bisect to
find which specific change introduced the bug, as described at [1].

Regards,
Jonathan
