There is quite a nasty bug in the NFS code that crashes the system if
the NFS exported disk has harderrors and you try to access that part
of the disk over NFS. If that happens the kernel jumps into debug mode
with the error code/msg

Panic: blkfree: freeing free block
stopped att _Debugger0x4: leave
