It happened shortly after the machine had fully booted, during establishment of the first sshd session. It nuked the machine really well, too. I had to pull the battery to get it back. fwiw: (gdb) l *0xc0126e7f 0xc0126e7f is in get_next_timer_interrupt (kernel/timer.c:863). warning: Source file is more recent than executable. 858 for (array = 0; array < 4; array++) { 859 struct tvec *varp = varray[array]; 860 861 index = slot = timer_jiffies & TVN_MASK; 862 do { 863 list_for_each_entry(nte, varp->vec + slot, entry) { 864 found = 1; 865 if (time_before(nte->expires, expires)) 866 expires = nte->expires; 867 } which looks reasonable.
