Ouch. Which other apps have you tried that hang the machine? Anything in
common? I can't really try to guess at what may be happening.

This is not good, it means the original RedHat kernel has the problem as
well. 

It would seem (probably) some kind of ALSA problem, maybe related to
using a particular access mode (probably mmap). Just a guess...
