I have the same problem although a bit different hardware (pvc740), but it uses the same module (pwc) Could it be because it (kernel or pwc module) now autodetects the need for snd-usb-audio? (save your work before loading that module). With kernels from 9.0 -> current cooker loading the pwc without the webcam attached actually works (no freeze). While loading snd-usb-audio always crashes on me. The kernel-multimedia-2.4.21.0.18mdk-1-1mdk worked with the webcam plugged in, but it did not load snd-audio-usb. Trying to load that module manually crashed the kernel. The current cooker kernel does not work with the webcam plugged in (from boot or hotplug). Frej Rasmussen > Regards, > > -- T.
