This is a 2.2 kernel from around the 8th or so, so I realise that this may
already have been fixed :

IdlePTD 21c000
current pcb at 1ddcdc
panic: pmap_release: freeing held page table page
[...ddb crud elided...]
#9  0xf011460a in panic ()
#10 0xf01b8719 in pmap_release_free_page ()
#11 0xf01b89f3 in pmap_release ()
#12 0xf01a55a8 in vmspace_free ()
#13 0xf01bc95a in cpu_wait ()
#14 0xf010ed21 in wait1 ()
#15 0xf010eb4f in wait4 ()
#16 0xf01bc69f in syscall ()
#17 0xf01b4385 in Xsyscall ()
...

I can build a kernel with debugging symbols to match if required, but if 
the answer is "get up-to-date" then I will. 8)
