Exactly. > If so, that's virtualbox's problem, I'd say. I can reproduce it on my host *alone* as I said in the very first message - never before I tried to run my Linux in a virtual machine.

And not otherwise? Yes, like I said earlier - only when I try to access its settings using Adobe Flash the system crashes/freezes. > Maybe you can describe in more detail what exactly you're doing so that > people could try to reproduce your issue. I don't think many people have the same webcam so it's going to be a problem. It can be reproduced easily - just open Flash "Settings" in Google Chrome 22. The crash will occur immediately. > > I'm CC'ing linux-media and linux-usb mailing lists, the problem is described here: > > https://lkml.org/lkml/2012/10/20/35 > > https://lkml.org/lkml/2012/10/20/148 > > Yes, good idea.

The > freeze below is a whole another issue. 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. Artem
