Can you please add this ...

Got this only after "recompile". "make clean" will make the warnings go away.

Well, it looks like a highres-timers problem or something
like that. So I can't really be handling that, as I have no
clue about this.
I suggest you also add Gary Zambrano <zambrano-dY08KVG/lbpWk0Htik3J/w@public.gmane.org>
here, as he is actually the maintainer of b44. Not me.
My role was just helping in debugging the issue, as I know
some details of b44.

I saw the same phenomenon on a totally other machine (therefore it's
likely something else):
Long periods (10-100s) of total unresponsiveness, not even SysRq-*
working.

In my case it was a HP nx6125, beeing unresponsive for about 5s, also
e.g. NUM Led did not work (but was still set after the unresponsive
phase ended).
Looks like machine got stuck with irqs disabled?

It came out that the problem was related to cpufreq (the real cause
probably came from ACPI subsytem). The freq was limited via processor
(_PPC) event and limitation got removed again at the same time, letting
the machine switching down and up it hang in powernow-k8.
Yes, it's unlikely that it's the same problem, but disabling cpufreq
should be worth a test?

Trying a kernel with CONFIG_DETECT_SOFTLOCKUP lockup should tell you at
which place the machine hangs?
