I'm seeing this, but my situation is ... reversed: my build machine came up OK: FreeBSD freebeast.catwhisker.org 10.0-CURRENT FreeBSD 10.0-CURRENT #1134 r2= 49538M/249542:1000030: Tue Apr 16 09:15:49 PDT 2013 root@freebeast.catw= hisker.org:/usr/obj/usr/src/sys/GENERIC i386 but my laptop exhibits symptoms that I *believe* resemble those you cited. (I was unable to get a crash dump, and the machine rebooted too quickly after I typed "panic" at the ddb prompt. I don't have a serial console on the laptop.) I had thought that it might be nvidia-driver-related (again), but I also note that the laptop has a single SATA drive, while the build machine has SCSI (possibly SAS -- machine is powered off for the day, since its work is done) drives. Laptop also has 2x the memory the build machine does. (They are each i386.) My last successful smoke-test for head on the laptop was yesterday: FreeBSD g1-227.catwhisker.org 10.0-CURRENT FreeBSD 10.0-CURRENT #869 r2495= 02M/249503:1000030: Mon Apr 15 05:23:38 PDT 2013 root@g1-227.catwhisker= =2Eorg:/usr/obj/usr/src/sys/CANARY i386 I had built head @r249538 this morning, and that's the build where my smoke-test failed.
