i recently got a athlon64 3500 and installed linux on it
first kernel i put on it was 2.6.9-rc3-bk7 so im not sure
if any other kernels before this have the problem
but basicly the problem is with uhci-hcd and ehci-hcd
modules loaded and if you start a compile and
randomly sometime after that i get a kernel bug showing up in
dmesg and it always seems to be due to cpudyn
or that is what is running when it happens not sure which
ive got a few errors saved and are below
these are from 2.6.9-rc4-bk1
motherboard is a 'k8t800 pro' chipset 939 socket (i wouldnt think
would make much diff tho)
i also have a skew in the clock perhaps its related
not sure how much its drifting but its alot
any other info needed ask away
ill attach the dmesg from the second error run
as its more complete
also it seems to need both usb hcd modules loaded
one or the other alone doesnt seem to trigger it
