Can you get a log from this happening with netconsole[1] or a serial
console[2]?  (It's ok if it doesn't catch the freeze --- it's just
that as full a log as possible of the context would be useful.)

If you can reproduce this with 3.5.y from experimental as well, please
report this upstream following instructions from [3] and let us know
the bug number so we can track it.

Thanks and hope that helps,
Jonathan
