Re: Repeatable md OOPS on suspend, 2.6.39.4 and 3.0.3

Hi.

Please try/review the attached patch.

The problem is that TuxOnIce adds a BUG_ON() to catch non-TuxOnIce I/O
during hibernation, as a method of seeking to stop on-disk data getting
corrupted by the writing of data that has potentially been overwritten
by the atomic copy.

Stopping the md devices from being marked readonly is the right thing to
do - if we don't resume, we want recovery to be run. If we do resume,
they should still be in the pre-hibernate state.

Regards,

Nigel
