[LAU] Is ALSA using hrtimer?

[Niels Mayer]

I added your suggestion to
https://bugzilla.redhat.com/show_bug.cgi?id=597354#c5 which resolves
the coredump in drumstick-sysinfo

///////// ///////// ///////// /////////
Upstream author Pedro Lopez-Cabanillas suggested doing
'sudo modprobe snd-hrtimer'
 prior to running Jackd.

Now drumstick-sysinfo doesn't crash. Furthermore, it looks like ALSA is using
the HRTimer:
