The problem is always present, no matter if - KMS is enabled or not - the agp/drm drivers are compiled as a module or compiled into the kernel - vesafb is used or not - tile blitting is enabled in framebuffer config space or not BTW: kernel 2.6.30.4 performs as bad as 2.6.31-rc6. >>From boot.log: <6>Linux agpgart interface v0.103 <6>agpgart-intel 0000:00:00.0: Intel 915GM Chipset <6>agpgart-intel 0000:00:00.0: detected 7932K stolen memory <6>agpgart-intel 0000:00:00.0: AGP aperture is 256M @ 0xc0000000 <6>[drm] Initialized drm 1.1.0 20060810 <6>i915 0000:00:02.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 <7>i915 0000:00:02.0: setting latency timer to 64 <6>[drm] DAC-6: set mode 640x480 0 <6>[drm] TV-12: set mode NTSC 480i 0 <3>render error detected, EIR: 0x00000010 <3>page table error <3> PGTBL_ER: 0x00000010 <3>[drm:i915_handle_error] *ERROR* EIR stuck: 0x00000010, masking <3>render error detected, EIR: 0x00000010 <3>page table error <3> PGTBL_ER: 0x00000010 <6>[drm] TMDS-8: set mode 1024x768 1a <4>Console: switching to colour frame buffer device 128x48 <6>[drm] fb0: inteldrmfb frame buffer device <6>[drm] Initialized i915 1.6.0 20080730 for 0000:00:02.0 on minor 0 >>From the Xorg log: X.Org X Server 1.5.2 Release Date: 10 October 2008 X Protocol Version 11, Revision 0 Build Operating System: openSUSE SUSE LINUX Current Operating System: Linux linux-golem 2.6.31-rc6-kape [...] (II) Loading /usr/lib/xorg/modules//drivers/intel_drv.so (II) Module intel: vendor="X.Org Foundation" compiled for 1.5.2, module version = 2.5.0 Module class: X.Org Video Driver ABI class: X.Org Video Driver, version 4.1 [...](II) [drm] DRM interface version 1.3 (II) [drm] DRM open master succeeded.
