Lockup on intel dri

[Colin Guthrie]

Hi,

I'm wondering if anyone can advice of how to address this lockup?

I'm running mesa master from a couple days ago + a few minor patches 
(quite similar to the Fedora dev package) + xserver 1.5.2 + patches 
(very similar to the Fedora dev package - I also cherry picked the dix 
backtrace stuff too). I'm using intel 2.5.0.

I'm getting the
[mi] mieqEnequeue: out-of-order valuator event; dropping.
[mi] EQ overflowing. The server is probably stuck in an infinite loop.
error but I know that's somewhat misleading.

As I have the backtrace cherry-picks from master the following was 
dumped into my log.
[mi] EQ overflowing. The server is probably stuck in an infinite loop.

I don't have anything special in my kernel and I'm not using GEM. My h/w 
is i945GM.

The above was with an older evdev, but (as it was mentioned, I upgraded 
to 2.0.99.2 and got the following (similar output):
[mi] EQ overflowing. The server is probably stuck in an infinite loop.

(evdev itself did odd things but that's another story!)


Any ideas?
