Subject: Re: kern/49707: i386 i915drmkms on 82845G/GL panic with Xorg intel
driver

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.

File ends here.
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.
