On my box (Athlon64-based) swsusp hangs forever in device_resume() called
from swsusp_write(), although interrupts are apparently handled
normally then (eg magic SysRq works).  The last thing it says is:

ACPI: PCI interrupt 0000:00:06.0[A] -> GSI 5 (level, low) -> IRQ 5
PCI: Setting latency timer of device 0000:00:06.0 to 64
ACPI: PCI interrupt 0000:02:00.0[A] -> GSI 11 (level, low) -> IRQ 11
ACPI: PCI interrupt 0000:02:01.2[C] -> GSI 11 (level, low) -> IRQ 11

When I press Alt+SysRq+p it says:

SysRq : Show Regs

This happens 100% of the time.  It also happened on 2.6.11-rc2-mm2, but not on
2.6.11-rc2-mm1, AFAIR.  It does not occur on the -rc[1-3] kernels.

Greets,
Rafael
