A small observation which I hope will be useful: I started getting unexpected lockups during mozilla sessions after remaking world & kernel on the evening of July 25. The screen would freeze completely, followed a few seconds later by a spontaneous reboot.
After this happened twice I deleted the new kernel and went back to using the kernel I compiled on the morning of the same day, July 25, and the crashes disappeared. I've cvsup'd and remade the world twice since then (but not the kernel) and I remain crash-free. Seems to implicate kernel code committed on July 25, sometime after about 1430 GMT.
