Resending. I could not see this going to the list, so I subscribed and am trying
again.

The following patch was reported to solve (at least some in the .32 case) hangs
on migration for 2.6.32 and 2.6.35 based kernels. I am not completely sure about
the 2.6.32 case as some reporters were reporting success after it was applied,
others still had issues[1]. But at least it seemed to improve the situation.
Should this get proposed for upstream longterm trees?
