Hi,

It sounds as if your harddisk is broken. As you can see, a lot of read
errors are being reported, before which GEOM finally gives up on your
disk (ad4) and detaches it from the system. Unfortunately, UFS is known
to cause panics if disks suddenly 'get lost', which is what triggers the
actual panic. 

I suggest you check your disk...
