I've had this happen twice now, running Andrew's "not quite -mm2" patch.
Symptoms: After about 20-30 minutes uptime, a running gkrellm shows system mode suddenly shoot up to 99-100%, and the keyboard dies. Oddly enough, a USB mouse continued working, and the X server was still quite responsive (I was able to close Firefox by opening a menu with the mouse and selecting 'quit', for example).
alt-sysrq-foo still worked, but ctl-alt-N to switch virtual consoles didn't. sysrq-t produced a trace with nothing obviously odd - klogd, syslog, and the disk were all working.
Nothing interesting in the syslog - no oops, bug, etc..
Another odd data point (I didn't notice if this part happened the first time): gkrellm reported that link ppp0 had inbound packets on the modem port of a Xircom ethernet/modem combo card. At the rate of 3.5M/second - a neat trick for a 56K modem. When I unplugged the RJ-11, gkrellm *kept* reporting the inbound traffic. When I ejected the card, *then* the ppp0 (and the alleged inbound packets) stopped - but still sitting at 99% system and no keyboard.
This ring any bells? Any suggestions for instrumentation to help debug this? [unhandled content-type:application/pgp-signature] | ![\](/images/icornerr.gif) |
