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.
