Bug#705526: linux-image-3.2.0-4-rt-amd64: Kernel panic as watching youtube in fullscreen(html5) regardigng ext4
Package: src:linux
Version: 3.2.41-2
Severity: critical
Justification: breaks the whole system
Dear Maintainer,
*** Please consider answering these questions, where appropriate ***
* What led up to the situation?
* What exactly did you do (or not do) that was effective (or
ineffective)?
* What was the outcome of this action?
* What outcome did you expect instead?
*** End of the template - remove these lines ***
Sometimes as I watch youtube videous in fullscreen (in HTML 5 mode) computer
either freezes, or a kernel panic occurs with functions in "Call trace"
regarding ext4. In some cases computer still works after the kernel message
occurs, but might freeze later if I continue to watch the video.
The only special configuration I use is "noatime" and "commit=60" in fstab.
The kernel error message:
