on this debian-PC the '-libre' are the only kernels with this issue.
but back to the actual problem:

The recent days have seen lots of fixes pass by on linux-rt-users. I
just read yesterdays: "hrtimers stuck in waitqueue"

quote by Gilles Carry: "Though the test hangs immediately on my ppc64 (8
CPU), it can takes tens of minutes on my x86_64 (8 CPU)..." - he
attached a patch to "fix a bug for high resolution timers initialized by
hrtimer_init_sleeper (nanosleep and futexes) which can get stuck on a
wait queue. They apply onto 2.6.26-rt1"

http://vger.kernel.org/vger-lists.html#linux-rt-users ;
http://marc.info/?l=linux-rt-users&r=1&b=200808&w=2

could be *the one* ;)
