Hello, I have a pcHDTV 3000 card [0], on a 3.10-rc6 kernel. Every so often, it stops working [1]. When I try to reload cx88_dvb, module loads, but init errors out because some sysfs file is already there [2]. Removing more of the video-related modules doesn't seem to help (at least not once this happens). Any ideas? It seems like this has been asked before [3] but no response. The files it fails to re-create are: [334698.061395] sysfs: cannot create duplicate filename '/devices/pci0000:00/0000:00:1e.0/0000:09:00.2/dvb/dvb0.frontend0' [334698.062420] sysfs: cannot create duplicate filename '/devices/pci0000:00/0000:00:1e.0/0000:09:00.2/dvb/dvb0.demux0' [334698.062881] sysfs: cannot create duplicate filename '/devices/pci0000:00/0000:00:1e.0/0000:09:00.2/dvb/dvb0.dvr0' And the other warnings are just fallout from that. After removing all of the video-related modules, that dvb directory is still there: # ls /sys/devices/pci0000:00/0000:00:1e.0/0000:09:00.2/dvb dvb0.demux0 dvb0.dvr0 dvb0.frontend0 # ls -l /sys/devices/pci0000:00/0000:00:1e.0/0000:09:00.2/dvb/dvb0.demux0 total 0 -r--r--r-- 1 root root 4096 Jun 30 23:03 dev lrwxrwxrwx 1 root root 0 Jun 30 23:03 device -> ../../../0000:09:00.2 drwxr-xr-x 2 root root 0 Jun 27 01:43 power lrwxrwxrwx 1 root root 0 Jun 27 01:43 subsystem -> ../../../../../../class/dvb -rw-r--r-- 1 root root 4096 Jun 26 21:43 uevent Note that subsystem there is a broken link, /sys/class/dvb no longer exists since I've unloaded those modules. Let me know if there's anything I should try. I'm pretty sure I can reproduce this at will (just reloading the cx88_dvb module should do it, even if the card isn't wedged) but I haven't tried it.
