Created attachment 24819 [details] dmesg.log with kernel 2.6.33rc6 Since at least kernel 2.6.31, I've been seeing an error message on every boot. Also, I can't suspend anymore my laptop because I always end with an X freeze, after a few minutes or a few hours (reported to X.org as [1]). This used to work in 2008. I'm not sure this is related at all, but the error looks serious enough to deserve a fix, even if it's to hide it! ;-) I'm using kernel 2.6.33rc6 on Ubuntu Karmic, with an Intel i915 graphics card (see output of lspci -vnn below). Please just ask if you need more informations. Thanks! 1: http://bugs.freedesktop.org/show_bug.cgi?id=23362 Excerpt of dmesg (see attached for full log): [ 1.672329] [drm] Initialized drm 1.1.0 20060810 [ 1.679888] ohci1394 0000:06:04.2: PCI INT C -> GSI 18 (level, low) -> IRQ 18 [ 1.712391] i915 0000:00:02.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 [ 1.712400] i915 0000:00:02.0: setting latency timer to 64 [ 1.716834] [drm] set up 7M of stolen space [ 1.736070] ohci1394: fw-host0: OHCI-1394 1.1 (PCI): IRQ=[18] MMIO=[b8008000-b80087ff] Max Packet=[2048] IR/IT contexts=[4/8] [ 1.842591] [drm] initialized overlay support [ 2.657547] fb0: inteldrmfb frame buffer device [ 2.657552] registered panic notifier [ 2.657571] [drm] Initialized i915 1.6.0 20080730 for 0000:00:02.0 on minor 0 [ 2.760156] render error detected, EIR: 0x00000010 [ 2.760159] page table error [ 2.760161] PGTBL_ER: 0x00000010 [ 2.760164] [drm:i915_handle_error] *ERROR* EIR stuck: 0x00000010, masking [ 2.760175] render error detected, EIR: 0x00000010 [ 2.760177] page table error [ 2.760178] PGTBL_ER: 0x00000010 [ 2.791522] Console: switching to colour frame buffer device 128x48 Relevant output of 'lspci -vnn': 00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller [8086:2592] (rev 03) Subsystem: Toshiba America Info Systems Device [1179:ff00] Flags: bus master, fast devsel, latency 0, IRQ 16 Memory at b0080000 (32-bit, non-prefetchable) [size=512K] I/O ports at 1800 [size=8] Memory at c0000000 (32-bit, prefetchable) [size=256M] Memory at b0000000 (32-bit, non-prefetchable) [size=256K] Capabilities: [d0] Power Management version 2 Kernel driver in use: i915 Kernel modules: i915 00:02.1 Display controller [0380]: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller [8086:2792] (rev 03) Subsystem: Toshiba America Info Systems Device [1179:ff00] Flags: fast devsel Memory at 64000000 (32-bit, non-prefetchable) [disabled] [size=5
Thanks. I marked this as a regression.
I get the same error on an EEE 701 with Ubuntu Lucid 2.6.32.10 another bug reports suggest a nomodeset can help [http://ubuntuforums.org/showthread.php?t=1357315]. I will try to post dmesg results after I get home and get access to the machine.
I am seeing similar errors after booting F12 on a ThinkPad X40 running kernel-2.6.31.12-174.2.19.fc12.i686. The system does continue afterwards.

These errors should be fixed now; turned out to be a bad alignment in our framebuffer code.
If you still see hangs with the drm-intel-next intel branch, please open a new bug since this particular one should be fixed now (the EIR errors on load).
Nice, drm-intel-next indeed fixes the warnings. But the freeze after suspend has now become a crash. I've opened Bug 26974 to track this. Thanks!
