Kernel Oops occurs on new PC about once per day. It was worse with previous BIOS and with proprietary nvidia graphics driver, but still occurs with latest BIOS and nouveau. Last time it happened while doing stress and gtkperf at the same time, but this time I was using thunderbird normally - I had just clicked on an email and the text console came up with kernel log. Mouse still moved, but keyboard appeared dead - but it had processed alt-sysrq-1, alt-sysrq-t. kern.log is now about 250Mbytes.
It runs 3 full passes of memtest86 with no errors. After BIOS update on Thursday, I loaded BIOS defaults and have not changed any settings since then. Max cpu temperatures even when running stress are 42deg.
