Hi,
Miles Lane (in CC) hit freezing failures in 3.2.0-rc4+ (Linus GIT af968e2)

Well, both tasks that refuse to be frozen hit page fault and are waiting
for data to be read from disk which apparently does not happen. Also there
were not any changes to speak of in ext3 for a while so I don't think ext3

I don't know ext3 that well, but could something have offlined the
storage while these tasks were waiting for their requests to come back?
Another hypothesis...could those requests require kthreads that got
frozen while processing these requests?
