Hello,

I had just rebuilt a kernel from sources dated 2002-05-19, rebooted,
logged in, and ran ssh when my system crashed, saying:

	panic: pmap_tlb_pool_page_free invoked

At that point, it dumped a core.  A backtrace from gdb says:

#0  0x1 in ?? ()
#1  0xc0264d49 in cpu_reboot ()
#2  0xc01c34d7 in panic ()
#3  0xc026c11f in pmap_tlb_pool_page_free ()
#4  0xc01c3228 in pool_allocator_free ()
#5  0xc01c2672 in pool_reclaim ()
#6  0xc01c275f in pool_drain ()
#7  0xc025bfa0 in uvm_pageout ()


It also crashed later this evening while I was in X (so it didn't dump).
This certainly isn't a regular occurence...this is the first time I've
seen this happen.

Thanks,
