[linux-audio-dev] crusoe ll problems

I'm trying to run a low latency kernel and audio applications on a crusoe processor laptop. Yes, I'm crazy. I have patched a 2.4.20 kernel with the low latency, preemption, and variable hz patches, as well as a modification to the alim15x3 DMA code and an extra entry in the "unusual USB devices" list. I'm running recent CVS checkouts of ALSA from Planet CCRMA. The kernel works well, and the low latency patches really make the system more responsive even under load. However, when I run latencytest0.42/do_test blah blah, the system hangs while playing the sound. It does not even display the xperf window. After a very long time, Control-C stops the process. When I run jack -R (jack 0.55) and freqtweak, freqtweak claims it gets "shut down" by jack the first time I try to start it. The second time I try to start it, it connects to jack and plays for a few seconds, but then audio stops and the system hangs. I need to use sysrq or a power cycle to restart. I can send pretty good beer, the alim15x3 patch, and any other clues to anyone who can help me with this. -- (jfm3 2838 BCBA 93BA 3058 ED95 A42C 37DB 66D1 B43C 9FD0)
