>Description:
First, I apologize for the vagueness of my report and for not trying it on RC-2 yet. The fact is I haven't had time yet, but I figured it is important to get your attention before RC-3 is released. :) I will follow up with any information you request. Thanks
AFTER I start playing, the kernel emits:
Interrupt storm detected on "irq17: ohci0"; throttling interrupt source
pcm0:play:0: play interrupt timeout, channel dead
pcm0:play:0: play interrupt timeout, channel dead
Oddly enough, sometimes mplayer will play up to about 10 seconds of a song, then start stuttering (roughly, playing each 0.5 seconds of music twice). xmms and amp never emit any sound, and appear to block as soon as they write(). Xmms's time-counter never advances past 00:00
>How-To-Repeat:
play an mp3 with xmms or amp
>Fix:
unknown
