Warmbooting from WinXP usually never works without re-plugging the USB
device, as the WinXP driver has loaded a different firmware into the
device, which stays alive there.

You need to run the complete oops message thru ksymoops to provide any
useful information.

But I'd first start to try a newer driver version, 0.11 from
http://at76c503a.berlios.de.

If you've got an UHCI hostcontroller, try to use the other driver (uhci/usb-uhci).

Try to build another kernel without usbdevfs support.

There were some discussions in the Berlios mailing lists about SuSE 9.0,
check the archives.
