I confirm that your patches on linux-acpi fix the problem.

I'm not dismissing the problem, but you seem to be the only person able to
reproduce it right and we have no clue about what can be wrong.
I'll try to prepare a debug patch

No change, sorry. As in all previous versions this sometimes works the very
first time after reboot; but second attempt in the raw still hangs.

There are several known places in kernel which break deadlock detection. Might
be we need one of the deadlock code authors to look into this...

I agree.
If the symptom is not reproducible without lockdep, it may indicate a lockdep
problem.

Do you have any output if you disable all spinlock debug?

There are some important fixes related to ACPI/suspend in the current Linus'
tree (2.6.23-rc7-git4 as of today). Andrey, can you test it, please?

More precisely, if a task is holding a spinlock, it can't be frozen (please
have a look at Documentation/power/freezing-of-tasks.txt in the 2.6.23-rc6
source tree for details).

The freezer only affects tasks in TASK_INTERRUPTIBLE.

Do I understand right, and we get interrupt while locked?
Does it mean that spin_lock_irqsave does not lock interrupts or we misuse it?
