Hi,
I have observed crash of 9vx when left idle (never crashed when doing anything).
I get this:
./9vx -t
init: starting /bin/rc
upas/fs: opening /mail/box/dima/mbox: '/mail/box/dima' does not exist
echo: write error: unknown control message "accelerated"
echo: write error: unknown control message "res 3"
-- at this point, 9vx is up and running, output below is at the moment of crash
cpu0: registers for stats 76
FLAGS=0 TRAP=500 ECODE=0 PC=14A5D USP=FFFFE10
AX 00000000 BX 0FFFFE50 CX 00000029 DX 00022F14
SI 0FFFFE68 DI 000336B0 BP 00000000
9vx panic: unknown trap/intr: 0x500
aborting, to dump core.
Aborted
9vx was checked from code.swtch.com and rebuilt, no effect.
Another time 9vx was more stable, but I got:
invalid opcode 67 6e 61 at eip 00021670
at some time after I started 9vx -t.
Hope this information is useful.

Died again (less than a minute after start)
I started 9vx -t, maximized 9vx window, killed acme and shell window
that are created by the profile, opened one shell window, did notning
in it, put 9vx window into background.
./9vx -t
init: starting /bin/rc
upas/fs: opening /mail/box/dima/mbox: '/mail/box/dima' does not exist
echo: write error: unknown control message "accelerated"
echo: write error: unknown control message "res 3"

9vx panic: unknown trap/intr: 0x500
aborting, to dump core.
Aborted
Another experiment.
Started 9vx -t, maximized window, put it into background. It was there
for several minutes, no crash. Then I killed initial acme and shell
window, started new shell window. It chashed:
init: starting /bin/rc
upas/fs: opening /mail/box/dima/mbox: '/mail/box/dima' does not exist
echo: write error: unknown control message "accelerated"
echo: write error: unknown control message "res 3"

One more kind of trap (did not cause crash) - not sure when exactly it
happened:
76 stats fault 0x33c no segment
segment 0xf000000 0x10000000
segment 0x1000 0x1b000
segment 0x1b000 0x22000
segment 0x22000 0x3a000
76 stats: unhandled fault va=33c [97df233c] eip=33c
cpu0: registers for stats 76
FLAGS=0 TRAP=0 ECODE=0 PC=33C USP=FFFFE48

Has anyone else seen these dumps with 9vx?

never seen anything like it, which leads me to wonder if you are not
tickling a bug in the virtualization.

It could be since it is "twice" virtualized ;)
