NetBSD forestiere 2.0.2 NetBSD 2.0.2 (GENERIC) #0: Wed Mar 23 01:25:37 UTC 2005  jmc@faith.netbsd.org:/home/builds/ab/netbsd-2-0-2-RELEASE/sparc/200503220140Z-obj/home/builds/ab/netbsd-2-0-2-RELEASE/src/sys/arch/sparc/compile/GENERIC sparc
>Description:
hardware configuration :
SS20 + 2x SM71 or 2x HM125 + cg14 + hme + 4GB sun/seagate hdd
************************
software configuration :
2.0.2 binaries from ftp.netbsd.org
UP kernel used (SMP kernel crashes too, but stack trace is from UP) on the 2x SM71 config
************************
Using X (cg3 emulation on cg14) easily crashes X, causing either a
"Level 15 interrupt" 
or a 
"watchdog reset" 
or a 
kernel panic  (2.0.2) with stack trace
************************
sample stack trace (I can generate others if needed, it's almost too easy) :
panic: illegal instruction
syncing disks... 20 20 20 20 20 19 19 18 18 18 17 17 16 16 15 15 14 13 13 12 12 12 10 10 9 9 8 8 7 6 6 6 6 giving up

NB : I have been unable to crash either OpenBSD 3.7 or Debian/Sarge (XFree 4.3 + 2.4.27).

>How-To-Repeat:
1/ full install of netbsd 2.0.2
2/ install the evilwm package (compiled for 2.0)
3/ put a .xinitrc with the only line "exec evilwm" inside
4/ start X
5/ launch an xterm on virtual desktops #1 and #2 

now :

* switching from desktop #1 and #2 (sc 1 and 2) back and forth does NOT crash (mouse is over only one xterm) which is obviously the expected behaviour

* switching from desktop #1 and #2 (sc 3 and 4) back and forth does crash after a few times (between 4 and 20) (mouse is over both xterms)

(2) http://tinypic.com/5catmr
(3) http://tinypic.com/5catn7
(4) http://tinypic.com/5catqd

addendum :
CTRL+ALT+1 (not numeric keypad) is used to activate desktop 1
CTRL+ALT+2 (not numeric keypad) is used to activate desktop 2
CTRL+ALT+ENTER is used to launch an xterm at approximately the mouse's position
