A little more information:
* My laptop (running the same sources, though a somewhat different
kernel config and a rather different hardware config) did not exhibit
the symptoms.
* A few other things occurred to me that might be of interest with DDB:
db> show pcpu 0
cpuid = 0
curthread = 0xd682d604: pid 11 "idle: cpu0"
curpcb = 0xd683dda0
fpcurthread = none
idlethread = 0xd682d604: pid 11 "idle: cpu0"
currentldt = 0x28
spin locks held:
exclusive (spin mutex) sched lock (0xc0335600) locked @
/usr/src/sys/kern/kern_idle.c:105
db> show pcpu 1
cpuid = 1
curthread = 0xda41a604: pid 289 "reboot"
curpcb = 0xda432da0
fpcurthread = none
idlethread = 0xd682d904: pid 10 "idle: cpu1"
currentldt = 0x28
spin locks held:
exclusive (spin mutex) clk (0xc0338ee0) locked @ /usr/src/sys/i386/isa/clock.c:415
db> show locks
exclusive (spin mutex) sched lock (0xc0335600) locked @

Locked vnodes
