Bug#584881: Lockups under heavy disk IO; md (RAID) resync/check implicated
FWIW, I was only able to reproduce the problem which I was seeing on
lenny+openvz (running the same workload on lenny+chroot, or
squeeze+openvz didn't trigger it).
The fix you attached does sound like a plausible fix for the issue I was
seeing (having spent a day or two peering at the code and sprinkling
printks all over it, but not ultimately getting anywhere), but I don't
think I still have my test environment archived anywhere. If I remember
correctly, things always ended up deadlocking with 1 request sitting in
md's queue.
Tim.
