I have no idea what triggered it. Did not have this problem with the 2.6.17 series which I am back to using now. I am using the proprietary nvidia module so if people think it helps I can try to recreate the problem without this module (might take a few days though). The logged call traces are not always completely identical here are some examples: Sep 24 13:29:24 gondolin kernel: Call Trace: Sep 24 13:29:24 gondolin kernel: [] thread_return+0x0/0xeb Sep 24
