Which kernel are you running? I had very similar problems with all 3.11
kernels below 3.11.5; kernel 3.11.5 works just fine for me. The 3.10
kernels also seemed to be okay, but the mailing list has suggested that
they may have some "time bomb" bugs, so you should probably be running
3.11.5 or newer.
Cheers,
Zach
