I can recreated the xrun messages 100% of the time and the routine in question never recovers. With a workaround suggested by Jaroslav, the xruns go away, but the calling process ramps up to 100% CPU utilization and unless you are on a dual or quad core machine there is quite a lockup. I revert to the 1.0.19 pcmlib.c in the 1.0.20 driver and I see neither problem. Thanks for all of your help Jaroslav. If there is any way that I can help debug this problem, please let me know.
