What I find strange is that I got the oops just as the benchmark is done and all process where shutting down. The same behaviour I reported here: http://www.ussg.iu.edu/hypermail/linux/kernel/0806.2/2113.html Only this time I got just one oops. This is on x86_64 system (4 Opteron CPU's and SW Raid 1+0). I have not seen this on my home system x86 (1 Dual Core and HW Raid). Anyway, here the dmesg output: kjournald2 starting. Commit interval 15 seconds EXT4 FS on md7, internal journal EXT4-fs: mounted filesystem with ordered data mode.
