Not sure what caused this to trigger, but it looks like
timekeeping_resume() isn't called with IRQs disabled (and the code
doesn't seem to expect that since it uses write_seqlock_irqsave).
hres_timers_resume() however calls retrigger_next_event() which does
require IRQs disabled and doesn't do that.
Like said, I'm not sure what caused this since the code in question
doesn't seem to have changed since April 2007.
Anyway, does the below patch cure trouble?

Hard to say because I do not know how to reliably trigger the BUG in the
first place. I'll keep watch with the patch applied. Thanks!

i've queued this up in tip/timers/urgent as it seems correct.
Rafael, can you think of anything in the s2ram code that would have
changed the irqs-off status of hres_timers_resume() in this codepath:

?
If not then maybe Andrey is the first one to get a successful lockdep
report out of such a situation - and this might have been a historic
high-res timers bug.

As far as I can tell, timekeeping_resume is called via class ->resume
method; and according to comments in sysdev_resume() and
device_power_up(), they are called with interrupts disabled.
Looking at suspend_enter, irqs *are* disabled at this point.
So it actually looks like something (may be some driver) unconditionally
enabled irqs in resume path.
I believe the patch should be hold back until this is clarified.

That's a nice theory!
I've queued up the debug check below instead. Probably the resume code
should include a similar check at a higher level and print out the
callback that enables irqs?

Add a debug check to test this theory. If it triggers then it
triggers because the resume code calls it with irqs enabled,
which is a no-no not just for timekeeping_resume(), but also
bad for a number of other resume handlers.

I would very much prefer adding a WARN_ONCE() or two into the resume part
suspend_enter(). Like this:

Well, it seems one of the notifiers does that.

I am absolutely confused. According to Documentation/power/devices.txt,
timekeeping_suspend and timekeeping_resume are class interfaces and allowed
to sleep. "Allowed to sleep" means to me - irqa enabled? But
device_power_down obviously runs under irqs disabled?

That's correct, device_power_down() runs with interrupts off, so
timekeeping_resume() is not allowed to sleep.
However, I suspect the problem is somewhere else.
Can you apply the patch I sent earlier in this thread
(http://lkml.org/lkml/2009/1/18/183) and retest?
