Marked as a regression. This should have been fixed in 2.6.33-rc7 with: commit 8a6c77d645d9111f7bc01f908464301f5c3e0a05 Author: Li Peng <peng.li@linux.intel.com> Date: Thu Jan 21 18:45:46 2010 +0800 drm/i915: Fix the device info of Pineview Pineview doesn't has CXSR and need GTT-based hardware status page. It fixes a X boot hung issue on Pinview since commit cfdf1f More details in http://bugs.freedesktop.org/show_bug.cgi?id=26439. Problem is not solved on Kernel 2.6.33-rc7-git2 for me. Neither can I start X nor am I able to switch to tty after xinit. There is no cursor anymore, only a black screen. Loading the i915 module manually causes a segfault. I will an attachment with dmesg error. Created attachment 24988 [details]
dmesg 2.6.33-rc7-git2
Relevant part of dmesg.
Shaohua, can you take a look? Wanted to write it yesterday, but there was a mysql problem with filezilla. Problem fixed in 2.6.33-rc8. |
Created attachment 24854 [details] kernel .config Impossible to start X with 2.6.33rc kernel, because there is nothing on the screen except the cursor. The cursor changes if you get over an icon(or better: the place where it should be). Switching to tty works. [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung render error detected, EIR: 0x00000000 Compiling 2.6.32.* kernel with exactly the same settings works just fine. Xorg log, output of dmesg, lspci -vxxx and lsmod and my kernel .config are attached.
