> Pretty much everytime I'm getting a lockup, i'm either streaming music from my music box or on a skype call. Not much to go by, but there isn't any logs left at all of the crash. It is not a panic (no writing dump to disk when I press enter, Caps-lock is dead, even the Fn key which is bound to the bios is dead). What I have noticed in these cases is that there seems to be a lock up....then, about a minute or so after it, the mouse seems to come back to life...but then there's nothing more I can do - i've waited for over 5 minutes after this with no more results....

btw, I've resorted to NOT using XMMS - the issues were happening a LOT more often when i use it instead of, say, vlc or beep.
I remember having this same issue on 6.2 with the drivers in the kernel. The latest binary drivers from Ariff would work fine, though i had given up on xmms by then and using vlc for a while.

If you find a solution and become attached to it, the solution may become your next problem.

I speak for myself, not my employer. Contents may be hot. Slippery when wet. Reading disclaimers makes you go blind. Writing them is worse. You have been Warned.
