Hi,
just got a panic on a fresh 1.4C system (today's sources with jason's vm
changes):
panic: pmap_page_remove: mapped managed page has invalid pv_ptp field
(gdb) where
#0  0xf01e210a in pmap_remove ()
#1  0xf01ddd83 in cpu_reboot ()
#2  0xf0137549 in panic ()
#3  0xf01e22ba in pmap_page_remove ()
#4  0xf01ca852 in uvm_anfree ()
#5  0xf01c9d6f in amap_wipeout ()
#6  0xf01c9646 in amap_unref ()
#7  0xf01cfa05 in uvm_unmap_detach ()
#8  0xf01cece5 in uvm_unmap ()
#9  0xf01d7ed0 in uvm_deallocate ()
#10 0xf012859a in exit1 ()
#11 0xf012841c in sys_exit ()
#12 0xf01e513a in syscall ()

This was while doing a 'make -j4 cleandir' in /usr/src (lots of fork/exec/exit).
Did someone else see this ?
