[Intel-gfx] Random blank screens

[William Grzybowski]

Hi,

I'm using the lastest git xf86-video-intel on arch linux kernel
2.6.27.9 ...
It is a Intel Corporation Mobile 945GM/PM/GMS, it is in a acer laptop
with lvds (of course), vga and s-video output.
I has been happening for some time now, i can't even remember when it
started but I keep getting a blank screen once in a while...
The screen gets black and the only way to get it working again is
reloading the i915 kernel module (just restarting the xorg doesn't
work)
When it happens i get a lot of: (EE) intel(0): underrun on pipe B! on
the logs...

I couldn't find a way to reproduce this, do you guys know something
about it?
Should I file a bug and add detailed information or do you have any
tips before go for this way?

Thank you!
