[Intel-gfx] recent intel commits cause X segfault

[Stefano Avallone]

Hi,

I am running kernel 2.6.30-rc8 on a GM965 with UXA and KMS and everything from 
git master:

libdrm: 85b9f737db0d2a845e4d7e2bbf9ad12ff9e2227c
mesa: 54576130a88fe93a64367f882cd680e37f0ec0ac
xserver: 7f027d9dc0146e229802aeac342ea2dbab63264a

Then, I updated xf86-video-intel from commit 
ea0b00e675281b2914450992501566122f9affe0 ("Provide mode line from VBT to 
xorg.") to commit 4afbe3b75e53cca1254883f2e847cf93cf9f0d71("Revert "Revert 
"Merge branch 'xvmc-vld'""). Now, I can start kdm but, before the KDE4 desktop 
can appear, the initialization process stops. Xorg.log shows (full version 
attached, I am using no xorg.conf):

Segmentation fault at address 0x53e58959

Fatal server error:
Caught signal 11 (Segmentation fault). Server aborting

I can reproduce this at every login into KDE.

Shall I open a bug?

cheers,
Stefano
