I was hammering on an alpha machine with make buildworlds last night,
and got this panic.  I've annotated the stack trace with the source
line numbers from the kernel I'm running (-current from Saturday, May
15):

(Transcribed by hand):

panic: warning: pmap_changebit didn't.

panic() at panic+0xf4 kern/kern_shutdown.c:449
pmap_emulate_reference() at pmap_emulate_reference+0x1ac alpha/alpha/pmap.c:2956
trap() at trap+0x2e4 alpha/alpha/trap.c:349
XentMM() at XentMM+0x20 alpha/alpha/exception.s:94
Lcs6() at Lcs6+0xc

Unfortunately (*whap*) I didn't (*whap*) have crash dumps (*whap*)
enabled, so that (*whap*) is all (*whap*) I've got.

(*whap*)
