freebsd stable - Jul 2009 - good old intel troubles

Now that the intel driver is stable and performs well, again, it's
time to start complainig about all the things that still do not work.

This is basically going to the console and back. Well, it actually
works but X will entirely lock up unless the mouse is in motion.
It's not hard to imagine that this is really bad. With violent mouse
movement I can get glxgears to render 0.3 frames per second.
That's it. 1 frame every 3 seconds.

Back on the console everything is fine, so it's really just X
misbehaving. No scheduling issue or the like.

Oh, btw, when I switch to the Konsole I get the following message
on my dmesg.
error: [drm:pid1318:i915_get_vblank_counter] *ERROR* trying to get vblank count
for disabled pipe 0

My system is a core2duo (amd64) running RELENG_7 (sources are from
~2 hours ago).

Maybe this snippet from my Xorg.0.log is also of interest:
(--) Using syscons driver with X support (version 2.0)
(--) using VT number 9

I'm running X without HAL.

These issues have been recently addressed in 8-CURRENT. I assume some 
MFCs will happen at some point.

This is still harmless, though I hope that I have caught most of the
cases where it occurs.  Userland (mesa) may still call this ioctl with
the wrong or both crtc's though.  It is converted back to a debug
message in HEAD.

This is all fixed in HEAD.  It is waiting jhb@ to MFC r194644 to get
-STABLE fixed up.  I have additional MFC's to cleanup vblank support
issues, but the primary issue is that msi interrupts don't work after a
vt switch without the above MFC.
