The same "sleeping function called from invalid context" happens with
2.6.14-1.1653_FC4 and 2.6.14-1.1656_FC4 but there is another nasty regress
here.

With 2.6.14-1.1653_FC4 I have to do 'modprobe -r button' on a laptop suspend
or a box goes into an infinite loop of suspend/wake-up cycles.  If I will do
'modprobe -r button' then I have to do 'modprobe button' on a wake-up or
I will be not able anymore to suspend with a power button or by closing a lid.
This can be automated in scripts used by "action" in /etc/acpi/even/*.conf
files so this is bearable if hacky.

2.6.14-1.1656_FC4 does not require the above but something worse happens.  Every
time I tried then on the at most second wake-up, and sometimes on the first one,
my laptop simply reboots instead of returning from a suspend.  Not very
useful.  It is better just to shutdown cleanly.  A wakeup after the first
suspend usually works but that is about it.

I do not need to mention that I do not have any useful log traces from such
reboots.  It appears that a laptop starts waking and then its screen blinks
and you are seeing a boot-from-scratch sequence.
