Description Miklos Vajna 2009-09-30 17:08:04 UTC 
Hello,

My card works fine with: xorg-server 1.6.1, kernel 2.6.31.1 and xf86-video-intel 2.7.1. I did a major test upgrade on a test partition and now my box hard freezes when X starts up and KMS is disabled. If I modprobe the i915 kernel module with modeset=1, then everything is fine.

Chipset:

$ /usr/sbin/lspci|grep VGA
00:02.0 VGA compatible controller: Intel Corporation 82852/855GM Integrated Graphics Device (rev 02)

System architecture:

$ uname -m
i686

xf86-video-intel/xserver/mesa/libdrm version:

xf86-video-intel 2.9.0
xorg-server 1.6.99.903 (hal support disabled)
mesa 7.6
libdrm 2.4.14

kernel version:

$ uname -r
2.6.32-rc2-dirty (in fact this is an unmodified 2.6.32-rc1 kernel, because the guys on #intel-gfx@freenode advised that I should try upgrading my kernel before I report a bug)

Linux distribution:

Frugalware Linux -current

Machine model:

Clevo M450C

Steps to reprouce:

Upgrade to xorg-server 1.7rc and xf86-video-intel 2.9, disable KMS and start X. It results in a hard freeze all the time.
