[linux-audio-user] amd64 jackd crash report

[cdr]

runs for a few minutes, then *boom* - heres a backtrace:

**** alsa_pcm: xrun of at least 0.585 msecs

generally similar to this, but not always the same, depending on the combination below:

jackd 0.99 or 0.100.7
gcc 3.4.5 or 4.0.2 or 4.1.0
linux vanilla-2.6.15 or gentoo-2.6.15 (-ingo randomly freezes on one, and reboots during boot on the other)
AMD a64-3000+ or turion mt-37
audio: ac'97 or echoaudio

i probably havent tried ALL the combinations - proably 80% of them. some time if im feeling motivated i'll do a full -g recompile of everything.. in case that might provide more clues. i just figured i should be able to get at least one of the two machines working right. but after excessive dragon-chasing have resigned to defeat.. even if jackd didnt crash, its not like my favorite audio apps pd or chuck would work right yet :)

oh, i can play mp3s in amarok thru XINE fine btw..
