i have a new computer, gigabyte GA-MA78GPM-DS2H, usb sometimes quits working. just now i tried to unload the module and reload it, but it hangs when i try to rmmod ehci_hcd. does anyone else have an amd southbridge that works or does not work with usb ?

this board is also randomly locking up. i am about to RMA the board and not sure if the amd south bridge just doesnt work, bad board, or kernel issues. if it seems that i just have a bad board ill get a new one of the same model. if this doesnt work for anyone, then perhaps amd was a bad choice ?

btw, i am cross posting on gentoo to get a larger audience to quicky resolve my hardware issue.
