It doesn't generally produce a kernel crash -- generally the device just stops working properly, and I get almost random noise on the screen, with the occasional glimpse of a picture -- just as if I had really bad reception. Rebooting fixes it, but unloading and reloading the module does not. I haven't seen a kernel crash since changing drivers, but it was fairly occasional anyway. I'll keep trying to see if it eventually crashes. Other than that waiting for another crash, is there any other way I can try to find the problem? Presumably there's no way to use electric fence or valgrind on a kernel module -- is there anything else?
