Lots of sparcs in a funny state?

Kevin reported that after the E40 router outage, a number of sparcs in
W20 and M11 were found at the "ok" prompt, right after running
gettime.
I asked him to get a crash dump, and it looked like this:
m11-113-5# adb -k unix.0 vm*
$c
physmem 1e6b
complete_panic(0xf0048bb0,0xf03e5a4c,0xf03e58d8,0x3,0x0,0x1) + f8
do_panic(?) + 1c
vcmn_err(0xf015f848,0xf03e5a4c,0xf03e5a4c,0x0,0x0,0x3)
cmn_err(0x3,0xf015f848,0xf015fc00,0x29,0x29,0xf0152400) + 1c
die(0x1,0xf03e5b54,0x0,0x164,0x3,0xf015f848) + 78
trap(0x1,0xf03e5b54,0xf017d36c,0x164,0x3,0x0) + 31c
fault(0xf00401a0,0xffeff000,0x0,0x71e1000c,0x80000000,0x0) + 84
prom_enter_mon(0x44000e3,0x44000e3,0xf0152b78,0x44000e3,0x4,0x10) + 60
debug_enter(?) + d8
abort_sequence_enter(0x0,0xfc0fd72c,0xfc0fd72c,0x0,0x29,0xf0152400)
kbdinput(0xfc01d018,0x4d,0x4d,0x0,0x1,0xfc01d040) + 2cc
kbdrput(0xfc1c6380,0xfc1c6338,0xfc1c6338,0xfc01d018,0xfc1c6348,0xfc18acc0) + 130
putnext(0x0,0x40000000,0xffffffff,0xfc1c6338,0x0,0x10) + 70
callout_execute(0xf01744c0,0xf0175aa0,0xc19d0,0x80000000,0xfc14788c,0x900111d0)+ 90
callout_thread(0x0,0x0,0xf01878c8,0xf01878c8,0xf01744d4,0xf01744c0) + 24
Everything between complete_panic() and fault() is caused by
Kevin forcing the dump. The rest strongly implies that someone
paraded around various clusters pressing STOP-A, but
it's conceivable there's some more subtle bug at work here. Especially
since some machines were found like this that were in alarmed
locked rooms (eg: gaston).
Crash dump for this one is sitting on m11-113-5 in /var/crash.
