Steve,

I think it's related to frequency scaling; I didn't have any problems
on my old Epox Mobo but I recently switched to an ASUS one. Switching
off any form of frequency scaling (powernowd, cpufreqd, ondemand...
governors...) fixed the problem. A friend noticed the same thing.
For now I manually switch to a higher frequency when needed and if no
recording is running. A bit of a PITA but no corrupted recordings
anymore.
