| |
I've had occasional apparent hard lockups on one computer here for some time. I'd previously been not doing much about it other than pressing the reset button, since there was nothing which marked it as a kernel panic (no blinkenlights; USB keyboard). However, I'd decided to make use of netconsole; this eventually logged the panic at the end of this message.
The kernel is 2.6.23.17-hrt5 (I had to do a few manual fixups, but nothing non-trivial); the DVB modules come from v4l-dvb (cset 127f67dea087); the attached mouse patch is in use (my mouse is weird).
The board is an Abit KN8 v1.1 (nForce 4); on-board ethernet is in use. Full kernel log & config are attached.

There is nothing so small that it can't be blown out of all proportion.
