2.6.19-rc6-mm2 oops and udev misbehavior
Seeing this oops on 2.6.19-rc6-mm2 intermittently on bootup. Also, when
this doesn't happen it seems like udev goes crazy adding and removing
/dev/md0 over and over using up a ton of CPU. Is this a known problem?
This also happened with -mm1.

Yes.... There is a patch in -mm called
md-change-lifetime-rules-for-md-devices.patch

which tries to remove md devices when they are no longer needed.
However it is racy, and it seems to be impossible to close the race
without making changes in core code as well.

For now, just revert that patch.
Andrew: you can drop that patch and the two related one. This is
going to need a lot more thought, and I'm not sure it is worth it
at the moment.

Thanks,
NeilBrown
