You don't get me - I have *no* VirtualBox (or any proprietary) modules

Ok, good. We got that out of the way - I wanted to make sure after you
replied with two other possibilities of the system freezing.

- but I can reproduce this problem using *the same system running
under* VirtualBox in Windows 7 64.

That's windoze as host and linux as a guest, correct?

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. Please, just forget about
VirtualBox - it has nothing to do with this problem.

It's almost definitely either a USB driver bug or video4linux driver
bug:

And you're assuming that because the freeze happens when using your usb
webcam, correct? 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. Maybe the folks there have some more ideas how to debug
this.

I'm leaving in the rest for reference.

What should be pointed out, though, is that you don't have any more
random corruptions causing oopses now that virtualbox is gone. 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.
