Background: Beginning around 5 PM EDT Sept. 21 I upgraded world and rebuilt my kernel; after rebooting to install the new kernel at about 9 PM, the system panicked and tossed something like this on the console (I'm working from memory; it was late and I was tired): Fatal trap 12: page fault while in kernel mode followed by a bunch of other text, "no dump device", and then a "reboot in fifteen seconds" countdown. The process seemed to hang somewhere around initializing or querying the mouse, a Razer USB. I rebooted and chose kernel.old; it works fine; and it looks like the code (I'm working on an uninformed hunch here) for moused.c did change just before the time I upgraded source. http://www.freebsd.org/cgi/cvsweb.cgi/src/usr.sbin/moused/moused.c.diff?r1=1.70.2.5;r2=1.70.2.6;f=h Again: I'm guessing based on what I see failing in the boot process; and on the things I can find that changed in the source tree: I can see other things that changed at about the same time; for instance, kld.3, kld.c,libutil.h in /usr/src/lib/libutil/; it looks like these things are relevant to loading ums(4) bits. Any clues? If the only way to investigate further is to build a debugging kernel and configure a dump device, I'm afraid I cannot build any sort of debugging kernel; I am pretty sure it would render my machine unusable and given that I've just reinstalled it on June 16, I'd rather not risk it.
