It also happens when someone plugs an adapter into the machine when the modules are already loaded. E.g. someone plugging a second adapter in, or unplugging and then replugging the same one. > Maybe the proper fix would be to change the logic under > em28xx_usb_probe() to not hold dev->lock anymore when the device is > loading the extensions. I could certainly write such a patch, although I only have a PCTV 290e adapter to test with. Is this problem unique to the em28xx-dvb module? How does the em28xx-alsa module get away with creating ALSA devices without causing a similar race condition?
