For me it is repeatable (on both a laptop and a desktop machine so it
does not appear to be very hardware specific). It might be of course an
interaction with the Fedora patches I use. 

In the category of "I wish I had a crystal ball" reports with no hard
data, I can confirm that my build of rt4 does hang. I was trying
2.6.29.1-rt4 during a rehearsal for a concert yesterday[*] and after a
hard hang I reverted to the vanilla Fedora kernel (which is what I had
been using because of that problem - no clues left behind in logs).

[*] a T61 lenovo laptop with intel graphics running jack 1.9.1,
linuxsampler, supercollider with two instances of the synthesis engine
doing both audio and midi processing, a convolution reverb using jconv,
ambisonics decoding through two instances of ambdec and the java based
swingosc supercollider gui. Very loaded.
