Hello, I think i didn't explained myself: With 6.2-PRERLEASE I tested mpg123 in the console and it played fine, no problems. When I start kde it will panic with kernel trap 19 being the criminal proc "artsd". If I skip artsd it will run just fine (like now). With -CURRENT I've used KDE also but don't remember if I used artsd in any ocasion. It worked with applications like mplayer or amarok. I could only repro this problem with artsd, everything else works just fine.. Dont think that its related to the link you posted. Also, I haven't crashdumped anything for ages, my kernel has the "makeoptions DEBUG=-g" and I've set dumpdev to my swap device ad03b (/dev/ad0s3b none swap sw 0 0) but this is what I get: Checking for core dump on /dev/ad0s3b... savecore: no dumps found And when it panics I see it saving the stack trace. Anything changed in the stack trace recovery process? Thanks for the help.
