image capture of panic and backtrace

I have a panic, saved in a .png, I'm going to try to write it out:

dev = da0s1f, block = 210733008, fs = /usr
panic: ffs_blkfree: freeing free block
cpuid = 3

Now the kern.version:

Now the kernel config file:

# What follows is a list of drivers that are normally in GENERIC, but either
# don't work or are untested with PAE.  Be very careful before enabling any
# of these drivers.  Drivers which use DMA and don't handle 64 bit physical
# address properly may cause data corruption when used in a machine with more
# than 4 gigabytes of memory.
