The freeze happens on my *host* Linux PC. For an experiment I decided to check if I could reproduce the freeze under a virtual machine - it turns out the Linux kernel running under it also freezes.I know that - but a freeze != oops - at least not necessarily. Which means it could very well be a different issue now that vbox is gone. Or, it could be the same issue with different incarnations: with vbox you get the corruptions and without it, you get the freezes. I'm assuming you do the same flash player thing in both cases? Here's a crazy idea: can you try to reproduce it in KVM?OK, dismiss VBox altogether - it has a very buggy USB implementation, thus it just hangs when trying to access my webcam.
Ok.
What I've found out is that my system crashes *only* when I try to enable usb-audio (from the same webcam) - I still have no idea how to capture a panic message, but I ran "while :; do dmesg -c; done" in xterm, then I got like thousands of messages and I photographed my monitor: http://imageshack.us/a/img685/9452/panicz.jpg
A hint at least. How did you enable the audio record exactly? Can you reproduce this with arecord? What chipset are you on? Please provide both "lspci -v" and "lsusb -v" dumps. As I said, I fail to reproduce that issue on any of my machines.
