Mybe I am wrong, but if you are detecting 40-wire cable to set them to DMA/33, why the check includes also 80-wire cables configuring them to DMA/33 too? With this patch my nvidia4 IDE controllers detects correctly and configure correctly DMA/100 for my HD and DMA/33 for my DVD (the first

I did the test you asked and yes, it is consistently booting at DMA33 with 2.6.20 and DMA100 with 2.6.19.3 (20 reboots, 10 2.6.20 and 10 2.6.19 in sparse order). I am compiling a 2.6.20 kernel with older pata_amd.c driver and will let you know. seeing the diff I do exspect it to compile

As I reported when I tested this patch, it works, but I could see an abnormally high load averay while triggering the error message. anyway, it is better to have an high load averag three or four times higher than what you would expect then a crash/reboot. isn't it? :) Luigi Genoni p.s. will
