Hello, Same to me with kernel 2.6.31.9-174.fc12.i686.PAE. I have an IBM with intel graphics card, that is always freezing. More details, please ask. Thanks. I have a related problem: my Dell Latitude D505 (i915 graphic chipset) flashes red-green-blue-black-white from very early in kernel boot sequence, even before starting services. I got this in messages log: J Jan 30 11:53:05 pamovi11 klogd: input: Video Bus as /devices/LNXSYSTM:00/device:00/PNP0A03:00/device:1e/input/input7 Jan 30 11:53:05 pamovi11 klogd: ACPI: Video Device [VID] (multi-head: yes rom: no post: no) Jan 30 11:53:05 pamovi11 klogd: ACPI Warning (nspredef-0437): \_SB_.PCI0.VID2._DOD: Return Package has no elements (empty) [20090320] Jan 30 11:53:05 pamovi11 klogd: input: Video Bus as /devices/LNXSYSTM:00/device:00/PNP0A03:00/device:24/input/input8 Jan 30 11:53:05 pamovi11 klogd: ACPI: Video Device [VID2] (multi-head: yes rom: no post: no) Jan 30 11:53:05 pamovi11 klogd: [drm] Initialized drm 1.1.0 20060810 Jan 30 11:53:05 pamovi11 klogd: i915 0000:00:02.0: PCI INT A -> Link[LNKA] -> GSI 11 (level, low) -> IRQ 11 Jan 30 11:53:05 pamovi11 klogd: integrated sync not supported Jan 30 11:53:05 pamovi11 klogd: [drm] DAC-6: set mode 640x480 0 Jan 30 11:53:05 pamovi11 klogd: integrated sync not supported This is booting with kernel-2.6.30.10-105.2.4.fc11.i586. However, when I boot with kernel-2.6.29.6-99.fc10.i686, everything's fine. It looks like the kernel is erroneously detecting the graphics hardware as i915, while it's a 855GM. I just added the option i915.modeset=0 to switch off KMS and now it works OK.

Makes things a little bit ugly, but its ok until it's fixed... @ Alberto, it is saying i915 because that is what the driver is called. It supports the older 855 chips also. And disabling KMS disables these codepaths, so you do not get the error. But that will not be an option any more with F13 as Intel has removed the old UMS support from their Xorg driver, so it is important to get it fixed. Also I have a suspicion your problem is different and unrelated to this bug report. In any case, I am seeing the same i915_handle_error on my old ThinkPad X40 with 855GM, and found an upstream bugzilla.kernel.org report on it. http://bugzilla.kernel.org/show_bug.cgi?id=15187 Hi all, I had the same problem after upgraded my ThinkPad X40 from Fedora 11 to 12. The kernel version: 2.6.31.12-174.2.19 If I added the option i915.modeset=0,then I got a blank sreen. Any idea? Thanks Upstream bug report was closed with the following comments: Comment #4 From Jesse Barnes 2010-02-19 20:33:15 (-) [reply] ------- These errors should be fixed now; turned out to be a bad alignment in our framebuffer code. ------- Comment #5 From Jesse Barnes 2010-02-19 20:37:05 (-) [reply] ------- 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). --------- So now it is waiting for these fixes to be merged into the Fedora F12 kernel Not seeing this any more with kernel-2.6.32.9-70.fc12.x86_64 out of updates-testing Fixed for me with kernel-2.6.32.9-67.fc12.i686 from updates. With the last available fedora kernel (kernel-2.6.32.9-67.fc12.i686), both messages disappeared. "render error detected, EIR: 0x00000010" is gone from initial boot console. Fedora logo comes up a lot faster during boot sequence. "[drm] DAC-6: set mode 640x480 0" is no more flooding the /var/log/meesages. So this bug seems to be resolved. But another new (for me) negative message appears now : "[drm:drm_mode_rmfb] *ERROR* tried to remove a fb that we didn't own." This appears only once in the /var/log/meesages, and without any bad effect. This message is already related in Bug 539709. Yes, I see this too. Actually, my log files show that this error occurred as far back as Feb 10, which predates kernel 2.6.31.12-174.2.19.fc12. I can't check further back because only latest five logs (five weeks) and latest 3 kernels are kept. closing this as resolved in current release, based on various comments |
