I installed the snapshot as my first venture into the current tree. Mp3 skippage and loopage was very bad. The box in question is an amd k6-2 300 (lower than average in this list, i gather). Mp3 decoding is only a 15-18% processor load, yet -current would skip & jump even while doing nothing else. a note on "pcm0: hwptr went backwards XXX -> XXX" I did not get these in 4.0-release. (or at least didn't notice them in six months..) I got a lot of these in -current. I've gotten two of these so far since reinstalling 4.1.1-release a few days ago. (i think they coincided with a load of mp3 playing, two compiles, & a mv between hds on my dma-crippled ata controller (this is heavy for me & my 300)) (sorry if this thread is outdated, i've been following -digest til now) -- chuck chkno@home.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
