Thank you Manuel, but IO think the patch is not complete as we need to
re-enable PNP devices after we make a snapshot to make sure they are
working and can handle saving the data. Coudl you please try the patch
below?

PNP: fix restoring devices after hibernation

From: Dmitry Torokhov <dmitry.torokhov@xxxxxxxxx>

On returning from hibernation 'restore; callback is called, not
'resume'.
This fixes breakage introduced by commit

ALSO, YES, this second patch version does cure the issue, on here,
too.
Rafael,

Will you please take this patch in? It would also make sense to add it
to stable I think.

Well, it conveniently hasn't been sent to linux-pm.

OK, I'll try to find it in the linux-kernel archives.

Thanks,
Rafael
