dmesg when booting linux-image-2.6.30-1-686

Package: linux-image-2.6.30-1-686 (2.6.30-1, Debian/Sid)
System: Debian/sid, KMS enabled (module i915 modeset=1 loaded)
Processor: Intel Pentium M 1.70 GHz
Chipset: 852GM/855GM

After upgrading the kernel-image to linux-image-2.6.30-1-686 (Debian/Sid)
booting ends with a black screen,not starting X, no more key input.
This only happens when KMS is enabled by loading module i915 modeset=1
at boot time.
Loading module i915 modeset=0 boots normally.
This issue doesn't occur with linux-image-2.6.30-rc8-686 (snapshot 13741)
and previous releases from Debian kernel-archive.

This is dmesg after booting linux-image-2.6.30-rc8-686, which boots cleanly.

Reassigned this regression to DRI.

Have you tried bisecting this?

> Have you tried bisecting this?

No I didn't and I don't intend to do, sorry. I am using binary linux images from
Debian, don't compile the kernel myself.
I tried once more booting 2.6.30 after compiling the latest git version of xserver. This too didn't succeed. So I keep using rc8.

I can no longer check this bug entry, I am no more using this computer while the disk crashed.
Comment 9 Jesse Barnes 2009-08-07 17:46:46 UTC
Ok marking as unreproducible.  If you get your machine going again and still see this issue with recent kernels, please file a bug at bugs.freedesktop.org against drm/intel using the instructions at intellinuxgraphics.org/how_to_report_bug.html
