Installation done on 1.5TB SATA drive connected to an D945GCLF2 board
with Hyperthreading disabled in BIOS.

System was doing pretty much nothing (command prompt) and I got hit by :

dev = ad12s1f, block = 725797872, fs = /usr
panic: ffs_blkfree: freeing free block
cpuid = 1
Uptime: 2h14m45s
Cannot dump. Device not defined or unavailable.
Automatic reboot in 15 seconds - press a key on the console to abort
panic: bufwrite: buffer is not busy???
cpuid = 1

And then the system hangs (and does not reboot).

This is the second time I get this error today. Last time when the
system rebooted it started fscking and then I got hundreds of ACPI
Exception: AE_AML_INFINITE_LOOP error (reported
here: http://www.freebsd.org/cgi/query-pr.cgi?pr=139088)

State-Changed-Why:  
Can you please try to enable dumps and possibly automatically 
get the proper results by using textdumps? I think the current 
information is insufficient to get going. Thanks!
