Here's dmesg output with the new tarball (system timer is not used this 
time but that doesn't seem to change anything).

By the way, note, that not rate may cause oops but number of channles 
for example (wav that causes oops has mono mode and the one that just 
plays silently - stereo. Also the oops sample is 16bit, silent one is 
24bit).
