I can try that with the 2 kernels, but it will have to be after amanda is done with her nightly tour, which will take another 2.5 hours. By then I expect to be sleeping, or hope to be, its 1:30am here now.
Or maybe not, what do I do when "vmstat 1" prints its column headers and segfaults?: --- [root@coyote linux-2.6]# vmstat 1 procs memory swap io system cpu r b w swpd free buff cache si so bi bo in cs us sy id Segmentation fault [root@coyote linux-2.6]# --- cd'ing to /proc/1, and trying to "cat mem" gets me this: --- [root@coyote 1]# cat mem cat: mem: No such process [root@coyote 1]# --- Some of the other names there have content, but 'mem' seems to be a truely empty filename, marked: -rw------- 1 root root 0 Jan 12 01:32 mem but apparently inacessable.
This actually sounds pretty serious, and I did have a hard lockup in the night last night, had to use the reset button, but I think that was a cpu overheat, I'd run the heat up cause the missus was squawking about being cold.
I've rearranged things airwise and got the cpu down to below 70C. These AMD DX-1600 thoroughbreds really are genuine coffee boilers. I really should replace it with the cheapest barton cored one, but this ones been running that hot for 30 months now. Running seti 24/7 of course doesn't help. :)
Do I need YANP42.6 (Yet Another New Program 4 2.6)? Sorry, couldn't resist creating a new acronym. :)
