Is this one more stable?
With 2.6.12-rc2-V0.7.44-03, the P4/HT box has been stable all day. I'm seeing another BUG on boot, not kprobes related this time: Freeing unused kernel memory: 192k freed logips2pp: Detected unknown logitech mouse model 86 input: ImExPS/2 Logitech Explorer Mouse on isa0060/serio1 BUG: kstopmachine:1054 RT task yield()-ing!
