Open davix3f opened 2 years ago
attempted to install this driver with a new install of archlinux this afternoon, and sure enough i'm getting a similar error message,

Didn't find any similar issue, so I'm opening a new one.

Driver installs fine, both from AUR and compiling manually. It is also loaded correctly at reboot etcetera:
However, /dev/vide0 is not created.
modprobe -r bdc_pci
doesn't work, as the module does not exist in the first place. If I try tomodprobe -r facetimehd && modprobe facetimehd
the laptop freezes and hard reboot is required. Sometimes, however, the driver gets reloaded, and /dev/video0 is created, if I execute this command sequence:but most of the times even this solution just ends up in a frozen laptop. This the result of a
dmesg | grep facetime
after a clean reboot, to see what's happening when the driver is loaded during boot.I have no idea what the last three lines mean, but maybe you guys can get something out of it. I have zero knowledge nor experience in driver programming. Let me know if I can help in any way!
