Both new wintv500 (with samsung tuners sigh) DMA TIMEOUT'ed within 30mins the existing wintv500 (philips tuner) is still running OK. I dont see any ENC DMA ERROR b's anymore with this driver/kernel, but i do still get the TIMEOUTS > What chipset/CPU are you using BTW?

(untested disabling on the lastest build, this was 2.6.19.1 and 0.10.3) Definately no cpu frequency changer, disabled in kernel, and almost no processes running at all. Hardware wise lspci shows this (i'll get the exact chipset for you next week) 00:00.0 Host bridge: Intel Corporation 915G/P/GV/GL/PL/910GL Express Memory Controller Hub (rev 0e) 00:02.0 VGA compatible controller: Intel Corporation 82915G/GV/910GL Express Chipset Family Graphics Controller (rev 0e) I've got the kernel compiled with dynticks at the moment, i've turned that off and i'm rebuilding to see how that goes. Then to try changing the various kernel preemption settings.
