I get

panic: vm_page_activate: already active

with a traceback (courtesy of savecore & gdb -k) of

#0  0xf018f67b in boot ()
#1  0xf0117733 in panic ()
#2  0xf0184014 in vm_page_activate ()
#3  0xf0185b03 in vm_pageout_scan ()
#4  0xf01861b2 in vm_pageout ()
#5  0xf0106db5 in kproc_start ()
#6  0xf0106d31 in main ()

I don't have debugging symbols in the current kernel. This is on a machine
with 8Mb, 486/66, 1542B, Barracuda. It happens part way through a make
all in /usr/src. John, if you wish to quickly repeat this, build yourself
a kernel which has MAXMEM (or whatever it is), set to something like 4 or 6Mb,
and try doing a make world in /usr/src. It'll bite within the first 1/2 hour.
