I upgraded to 2.6.11 from 2.6.5 and it seems that was a mistake. My thumb drive no longer works with Linux and I get more xruns than ever; mostly on playback, which is odd. I didn't patch the kernel yet, all I did was use stock but I enabled the pre-empt this time. Last kernel didn't even have that. Anyone have some thoughts? I thought people where saying that post 2.6.10 was the best there was for audio. So far it doesn't seem like it. A have an amd64 and I am in 64 bit mode. Thanks for any suggestions.
