I have a system running, now its running a 2.6.34 but it also happend with 2.6.33.x and 2.6.32.x. I hit a BUG and the whole system hang. I had to reboot and the console was to small to show the full BUG. But now I got the framebuffer setup and could write the following dump down (by hand, so there might be some typos or so, I have a "screenshot" if you have a specific question) The system is a amd64 phenom X4 with 2 x 4GB non-ECC RAM and a raid6 for / and a data-partition as well as a raid1 for swap. I ran memtest86+ 4.0 and it showed no errors for two passes. An hour before that BUG I saw a lot of async-processes. It happens round about once a day, will check if its the same or similar the next time. But any hints are greatly appreciated! (How to solve or how to get needed informations.) Thanks, Markus PS: Please CC me.
