I am experiencing kernel hangs and panics when I leave the rc564 processes running for more than 30-60 minutes. Sometimes I get a kernel panic and somthimes the kernel hangs compleatly. In the case of a kernel panic the system loocks up after I press ctrl+alt+escape. My system is a dual PPro 200Mhz system using the intel PR440FX motherboard. The system is completly stable if I don't try to run the rc564 program. I have suspected that the hangs only appear when both processors are working at 100% utilization so I wrote a small C program consisteing of a while (1) do ; loop. But I have left 2 processes running this program for days with no crashes. Does anyone else experience kernel hangs/crashes running the rc564 program on FreeBSD 3.0-current (the last cvsup sync was 18/11-97) and using the SMP kernel?
