Looks like i915 is unstable with xorg-server 1.8.0. I recently updated world from a 2 years ago tabletpc, perfectly working configuration to the latest ~x86 tree, and I'm unable to use X, KDE4. I tried to play around with modesetting, compile i915 as a module or into the kernel, but I have the same error messages either way. Reproducible: Always Steps to Reproduce: 1. start xdm with kdm4 or xdm 2. login to kde4 OR click any button on the login screen xdm seems stable, and its own UI widgets don't lead to issues 2a. if kde4 started, click on any button (the "K" button for instance) 3. X becomes unresponsive, only mouse cursor moves. 4. optionally try to restart xdm from ssh, but kdm won't start anymore. Only X will start, and will only display the mouse cursor on a black background. Actual Results: i915 driver cannot be unloaded (busy), and both dmesg and Xorg.0.log display error messages related to the driver Expected Results: i915 should be unloadable/reloadable after killing X, and be stable dmesg says: i915 0000:00:02.0: PCI INT A -> Link[LNKA] -> GSI 10 (level, low) -> IRQ 10 i915 0000:00:02.0: setting latency timer to 64 [drm] set up 31M of stolen space [drm] initialized overlay support udev: renamed network interface eth0 to wl fbcon: inteldrmfb (fb0) is primary device Console: switching to colour frame buffer device 128x48 fb0: inteldrmfb frame buffer device registered panic notifier [drm] Initialized i915 1.6.0 20080730 for 0000:00:02.0 on minor 0 fbcondecor: console 0 using theme 'emergence' fbcondecor: switched decor state to 'on' on console 0 fbcondecor: console 1 using theme 'emergence' e100: lan NIC Link is Up 100 Mbps Half Duplex fbcondecor: switched decor state to 'on' on console 1 Bridge firewalling registered fbcondecor: console 2 using theme 'emergence' fbcondecor: switched decor state to 'on' on console 2 fbcondecor: console 3 using theme 'emergence' fbcondecor: switched decor state to 'on' on console 3 fbcondecor: console 4 using theme 'emergence' fbcondecor: switched decor state to 'on' on console 4 fbcondecor: console 5 using theme 'emergence' fbcondecor: switched decor state to 'on' on console 5 usb 2-1: new low speed USB device using uhci_hcd and address 3 input: Silitek USB Keyboard as /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1:1.0/input/input5 generic-usb 0003:047B:0006.0002: input: USB HID v1.00 Keyboard [Silitek USB Keyboard] on usb-0000:00:1d.0-1/input0 fbcondecor: switched decor state to 'off' on console 1 fbcondecor: console 1 using theme 'emergence' fbcondecor: switched decor state to 'on' on console 1 fbcondecor: switched decor state to 'off' on console 2 fbcondecor: console 2 using theme 'emergence' fbcondecor: switched decor state to 'on' on console 2 fbcondecor: switched decor state to 'off' on console 3 fbcondecor: console 3 using theme 'emergence' fbcondecor: switched decor state to 'on' on console 3 fbcondecor: switched decor state to 'off' on console 4 fbcondecor: console 4 using theme 'emergence' fbcondecor: switched decor state to 'on' on console 4 fbcondecor: switched decor state to 'off' on console 5 fbcondecor: console 5 using theme 'emergence' fbcondecor: switched decor state to 'on' on console 5 e100: lan NIC Link is Up 100 Mbps Half Duplex [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed...

Please paste your "emerge -pv xf86-video-intel" output.
[ebuild R ] x11-drivers/xf86-video-intel-2.11.0 USE="dri" 0 kB
Please paste the full output of dmesg when that message shows up, and please try the latest git-sources kernel (yes, without tuxonice...). Thanks

Greetings, I've also tried with 2.6.34-rc7. The dmesg output is different: this time it also talks about render errors. Attaching.. Cheers

Two things are notable from that dmesg: * video=intelfb:ywrap,mtrr:4,1024x768-32@60,splash=verbose,theme:emergence intelfb should not be used. It is not mentioned anywhere else in dmesg so it could be disabled in kernel already. Ensure it is. * Local APIC disabled by BIOS -- you can enable it with "lapic" * no APIC, boot with the "lapic" boot parameter to force-enable it. If the problem is due to an interrupt issue, maybe enabling lapic helps.
> * video=intelfb:ywrap,mtrr:4,1024x768-32@60,splash=verbose,theme:emergence removed (intelfb was not compiled. I removed it earlier, just forgot a reference to it in grub.conf), and replaced with lapic This time X lasts longer: I'm able to click the K button, which opens the menu, I open an application, and... crash again :) Attaching the new dmesg Cheers
Created attachment 231311 [details] latest dmesg with lapic enabled
Please try with the latest 2.6.35_rc kernel. If it still fails, please file a bug upstream [1] and paste the URL here so we can track the issue. Thanks
