[LAU] snd-hrtimer ALSA module

Has anybody successfully used the ALSA snd-hrtimer module, as present in
ALSA 1.0.18a and 1.0.19? It seems to cause lock-ups in just a few
seconds on a 2.6.27 kernel for me.

The backstory to this is that I am trying to use Rosegarden on a 2.6.27
non-realtime kernel (a backport for Ubuntu Hardy from the kernel PPA).
Rosegarden requires an ALSA timer (it cannot use /dev/rtc0 directly).
The system timer-based snd-timer module works at 250 Hz (too coarse) and
the traditional snd-rtctimer module is gone after 2.6.24. Therefore I
tried to upgrade ALSA and use the new hrtimer module, which as reported
doesn't work...

As to the real-time 2.6.27 kernel, which I am sure everybody will advise
me to use, it has some problems for me (including bad interactions with
other drivers leading to lock-ups).

Any thoughts?

Thanks,
Dan
