After some rebuilding and reinstalling of ports, I was able to cat /dev/cxm0 to a file in my home directory for about half an hour with no dma errors or lockups. I then stopped the cat and tried 'mplayer -cache 4096 /dev/cxm0', and my machine locked up after about 2 minutes. The display continues to update; my dockapps in fluxbox are still functioning and updating, but the machine does not respond to any network traffic or input devices and the video and audio from /dev/cxm0 have halted. Nothing is being logged to /var/log/messages at the time. I tried it again while keeping an eye on the console in case there are dma problems preventing anything being written to the log: cxm0:encoder dma status 0xb # MACHINE STOPPED RESPONDING HERE cmx0:encoder dma status 0xb ad0: TIMEOUT - WRITE_DMA retrying (1 retry left) LBA=22069947 ad0: TIMEOUT - WRITE_DMA retrying (0 retries left) LBA=22069947 dc0: watchdog timeout dc0: failed to force tx and rx to idle state ad0: FAILURE - WRITE_DMA timed out LBA=22069947 ad0: FAILURE - READ_DMA timed out LBA=20487259 The above messages continue to be output to the console and I have to manually restart the computer.
