12:49:00 samt kernel: PM: Finishing up.

As you can see, IRQ 9 gets stuck here and consequently, the next ACPI
event (e.g. lid button) causes a system freeze. Hoping that the problem
might relate to some uninitialized memory after resume I raised the
limit for unhandled IRQs in spurious.c (irq.c before 2.6.10). But that
does not help.
I'd really like to debug this but I need help from an expert where to
look at to find out what happens to this acpi IRQ.

Thanks,
	Fionn

Did any device share IRQ 9 with ACPI? If yes, please try unload the
driver.

No, according to /proc/interrupts, IRQ 9 is being used by acpi
exclusively.

any other ideas?
