It is a dual Xeon machine with hyperthreading. Since I've updated it, it has crashed regularly. So regularly that I have had to remove it from service. I built a debugging kernel and from my last crash dump I get the following: #0 doadump () at pcpu.h:159 159 __asm __volatile("movl %%fs:0,%0" : "=3Dr" (td)); Now, I'm in the fortunate position of not having FreeBSD crash usually, so I'm not sure what to do next. Can someone offer some help? Thanks, Frem.
