Patched 2.4.2-ac12 rebuilt usb-ohci.o and usbcore.o
Reboot with mouse plugged in.
demsg shows:
usb.c:registered new driver usbdevfs
usb.c:registered new driver hub
usb-ohci.c: 00:07.4 (....AMD-756 ....): blackliseted, erratum #4
usb.c: deregistering driver usbdevfs
usb.c: usb_hub_thread exiting
usb.c: deregistering driver hub
So it boots OK :)
and I cannot use any USB devices:(
Are there any debug settings I can use to
try and find wahat changed from ac4-ac5
that causes this bug to cause and oops?
I'm new to USB and kernel debugging.
