The problem has been identified as the known issue related to the XFS freez=
able
workqueues.  There is a patch available (http://lkml.org/lkml/2007/3/21/328=
),
that has been merged.

Still, there is a problem with the microcode update driver that's being wor=
ked
on.

The reporters of the resume problems who use the microcode driver, please
check if the problems go away if you unload the driver before the suspend.

Greetings,
Rafael
