>Description:
Dell Optiplex GX260 built-in video via i82845G/GL attaches i915drmkms
and intelfb drivers. Framebuffer console works. Xorg with "wsfb"
driver works.
Xorg with "intel" driver (in "xorg.conf" or autodetected) panics and
reboots machine near instantly. The "NoAccel" option has no effect.
"dmesg" and "var/log/messages" excerpts (machine is diskless/NFS root).

[panic/reboot]
If the console is on the serial port, i915drmkms disables the video
(VGA) output. Starting X then doesn't panic the machine, but instead
spins forever looking for an active output.

After attaching a local disk, I started xorg with console on video.
It panicked and successfully wrote a crash dump (and sucessfully recovered
it on the next boot.
Not sure if it's particularly helpful, but here it is:
$ crash -M netbsd.0.core -N netbsd.0
Crash version 7.99.5, image version 7.99.5.
System panicked: trap
Backtrace from time of crash is available.

driver

I was briefly able to run the Xserver with the intel driver in 7.99.9.
The machine had been running with the "wsfb" driver for several hours
displaying the 'xdm' greeter widget (IIRC, "wsfb" used to be able to do
DPMS screen blanking, but lately it cannot and the screen stays on all
the time--not good for a CRT and probably not good for LCD either). (I
cannot turn the monitor off due to kern/49398.)
To see if changes since my last post to this PR made any difference I
logged in, logged out again, then stopped 'xdm' (and the Xserver) by
pressing "Ctrl-R" three times at the login widget (why it insists on
performing "finish-field" instead of terminating immediately I don't
know).
The display didn't revert to wscons screen 0 automatically, so I switched
manually with "Ctrl-Alt-F1". I moved the "/etc/X11/xorg.conf" file that
specified the "wsfb" driver aside and started X manually:
$ X -retro &
It took a while and I was expecting the machine to reboot like it usually
does, but after a few more seconds, the X display appeared! With the
foresight to push the server in the background, I was able to switch
back to the original terminal and start a few clients and it worked
quite nicely.
Figuring that running with "wsfb" first might have caused some
initialization to occur that was missed starting the intel driver, I
stopped everything and rebooted the machine.
Alas, I am unable to repeat this event. I've tried staring the X server
with the "wsfb" driver and then restarting without any config (autodetect
intel driver), but doing so panics and reboots the machine as it has
in the past.

I was briefly able to run the Xserver with the intel driver in 7.99.20.
I noted with interest the following commit:
http://mail-index.netbsd.org/source-changes/2015/08/01/msg067839.html
and the similarity of "kern/49875" to this one.
Following an update, I ran:
$ X &
The machine switched virtual consoles and the "X" cursor appeared very
quickly. With the foresight to push the server in the background, I
was able to switch back to the original terminal and start 'xterm'
and it worked quite nicely, although cursor movement seemed to leave
the bottom scan line behind for a second or so.
When I stopped 'xterm' and its window closed, the root window behind it
showed the classic "root weave" pattern as if "-retro" had been used.
Staring a new 'xterm' and then 'twm', the weave pattern appeared in
any region the terminal window vacated.
Not thinking more of it, I stopped everything and re-launched X with
$ startx -- -retro &
which started the X server (with root weave retro pattern) followed by
the clients started by my '.xinitrc' file (urxvt and fvwm2 plus
accessories). I stopped and started everything several times. It seemed
to work very well.
Then I rebooted the machine. I have not been able to start the X server
since. It switches wscons terminals but the display never appears.
Switching back to the terminal from which it was started reveals:
Bus error.

The result is the same after rebooting several times. Starting with
the "wsfb" driver first has no effect.
So, an improvement: Starting X with the "intel" driver no-longer panics
the machine, but is unlikely to produce a working display.

As noted in:
http://mail-index.netbsd.org/netbsd-bugs/2015/08/03/msg041913.html
and subsequent postings, starting X no-longer panics the machine but
instead causes the X server to crash with Bus Error. It has been observed
to work on rare occasions, but it seems pure chance that it does. When
it does, it does so repeatably but following a reboot it will once again
crash with Bus Error.
I noticed some recent commits to i915drm and related items. I am in
the process of updating and building and will post the results soon.

`-V MKDEBUG=yes' for build.sh is correct. The symbol table
information is stored under /usr/libdata/debug, which is distributed
in the xdebug.tgz set.

I rebuilt with MKDEBUG=yes (and MKDEBUG_LIB=yes, just in case). I presume
I would issue something like:
# gdb -s /usr/libdata/debug/usr/X11R7/bin/Xorg.debug -e /usr/X11R7/bin/Xorg
In any event, I tried that, and 'gdb' claimed there were no debugging
symbols found. Running X still ends in Bus Error and the output is the
same as my previous post on the matter.
I suppose I need to do a non-update build if I've not built with
MKDEBUG=yes before? I'm doing that now. It will take some time.

you shouldn't need to specify the debug info file directly, it should
be referenced such that GDB will find it.

another method is to set "DBG=3D-g -O2" in mk.conf or environment when
building (without MKDEBUG). this leaves full debugging info in the
normal binaries..
i don't know what's wrong that it isn't working yet, but either try
using gdb normally, or, try building with DBG as above.

Yes, more or less. It's sufficient to delete the objdirs for Xorg and
any of its libraries, but easier to rebuild everything.

I had occasion to try modular/pkgsrc Xorg. It behaves the same: Bus error.
Although I built the server with the "debug" option, it doesn't sseem
to have any debugging symbols. The backtrace from 'gdb' seems to be
otherwise consistent with the "native" Xorg.

I rebuilt "modular-xorg-server" and "xf86-video-intel" with:
CFLAGS+= -g -O2
I didn't get any more debugging symbols, but the resulting Xserver
doesn't crash. An initial trial under 'gdb' seemed not to produce a
working display. The screen was blank (the wscons cursor was not visible)
but there was no X cursor. Attempting to switch virtual terminals
appeared not to work. It reported receiving "SIGUSR1".
Later, running 'X' normally, with the "-retro" option displayed the
"root weave" pattern, and opening 'xterm -display :0' worked.
So, Heisenbug?

Nevermind. It was one of those rare flukes where it sponaneously started
working. After rebooting the machine, it crashes with Bus Error the
same as before. There's a little more debug information, but not much:

How do you start X after a reboot?
If that's from xdm run from the rc scripts. Does the crash happen
when you start it later, even with '/etc/rc.d/xdm onestart' ?

On this machine, starting the X server is completely manual since it's
pointless to do otherwise until the cause of the crashing can be fixed.
So, most commonly:
$ X -retro &
or, if I'm feeling hopeful:
$ startx -- -retro &
or, for debugging, via SSH:
$ sudo gdb X
(gdb) run

As of 10 March with sources from around 201603100400Z, the behavior
with pkgsrc Xorg (pkgsrc-2015Q4) is the same as previously posted.
Likewise, the results of "native" Xorg are the same as the time
previously posted (13 Oct 2015).

Now that many updates have been made to the xsrc tree--particularly
Xorg xserver 1.18.4, I decided to see what impact it had on this PR.

So, it appears there is no change.
Also, perhaps this PR should be re-categorized from "kern" to "xsrc".
The original problem of panicking upon starting the X server with the
"intel" driver seems no-longer to occur. Instead, we get bus error.
as noted above and previously.

After nearly four years, I've finally had opportunity to test the target
machine of this PR again. In that time, changes to i915drmkms and/or
Xorg/intel driver seem to have overcome this problem (9.99.59). The
target machine seems to run Xorg without issues, no "xorg.conf" needed.
If one wants intel XvMC enabled, an "xorg.conf" file will be required.
The only mention of any acceleration for the device is:
composite (RENDER acceleration)
I'll try again after the next build of -current but it looks like this
PR may finally be closed.

Yes, the i82845 integrated graphics device now works very well with Xorg.
It even works properly with SNA w/o TearFree (relevant to another PR).
This PR may be closed.
