Hello,
When I was copying a lot of information (tens of gigabytes) from my primary HDD
to a
secondary HDD I got gazillions of errors like these ones:

Hello,
I have a P8P67 Pro motherboard made by ASUS and recently I decided to switch to
EUFI boot.
Maybe it's a coincidence or maybe Linux kernel 3.7.6 (vanilla) has some serious

On boot I have:
HDD write performance: ~12

Hi,
I can only reproduce this panic when my USB webcamera is plugged in - when
I click settings in Adobe Flash it sends some commands to my USB webcam using,
presumably, Video4Linux API calls which cause a kernel hard crash.

I'm resending my last email since the first one didn't draw enough
