Now, there's some kind of issue with that timer. It needs to be split out on its own, rather than trying to multiplex with other timers. There was a patch circulated a while back that improved the situation in some case. However it also caused problems in another case, so it was reverted. I never had a chance to go back and come up with a better fix ... in large part because it never reproduces on hardware I've got (I don't run VIA chipsets). If you want to try coming up with a fix yourself, you can check the GIT history, ehci-hcd.c was modified. - Dave ------------------------------------------------------------------------- Take Surveys.
