Another two spontaneous reboots today. Latest one occured whilst I was away from the computer, output is below. A different call trace this time. No response to my previous report, so adding some e-mail addresses from get_maintainer.pl / git blame.
It's an old graphics card, and this time I note references to RAM and memory. Is there any possibility it's hardware? Is there a GPU equivalent to memtest86+ ?
