Hi,
The video driver doesn't properly remove all the notify handlers on module
unload. This has a side effect of subdevices failing to register on module
reload, but sudden death looms if the handlers trigger after the module is
unloaded (not that I've seen such a machine, but still). Please apply.
Best regards,
