Package: xserver-xorg-video-intel
Version: 2:2.4.1-1 (experimental)
System: linux 2.6.26-1-686, chipset 852GM/855GM
Severity: normal

Since I upgraded xserver-xorg and mesa from unstable to experimental I get the following error in xorg.log:
(EE) intel(0): underrun on pipe B!

Cheers,

I can find some similar bug reports in the upstream bugzilla but most of
them seems to be fixed now.

Our 2.4.1-1 actually contains upstream 2.4.2, and I am not sure that a
2.4.3 is ever planned. So your only hope might be to try git master, but
I am not sure it can be compiled easily in Debian.

Otherwise, you can go back to <2.4.1-1 (snapshot.debian.net doesn't seem
to contain one of them for Xserver 1.4.99/experimental, so you'll have
to build the intel driver).

The problem has been reintroduced for me with 48d4b0a. I reported it to
Jesse on #intel-gfx, but haven't filed a bug.

The latest git version from xf86-video-intel still shows the same error on my system.
I compiled xserver-xorg-video-intel version 2.3.2-2 (unstable) for Xserver 1.4.99 (experimental)
and it works without errors!

Is the problem gone for real with other recent intel driver in
unstable or in experimental?

Using video-intel driver version 2.7.99.901-2, xorg.0.log doesn't show any error.
