Do you have some kind of fbdev driver loaded? Just asking as that completely changes the unload code path to something I've never tried (In reply to comment #1) > Do you have some kind of fbdev driver loaded? Just asking as that completely > changes the unload code path to something I've never tried Yes, I do. I didn't know it could matter: Linux agpgart interface v0.101 (c) Dave Jones agpgart: Detected an Intel 855 Chipset. agpgart: Detected 8060K stolen memory. agpgart: AGP aperture is 128M @ 0xd8000000 intelfb: Framebuffer driver for Intel(R) 830M/845G/852GM/855GM/865G/915G/915GM chipsets intelfb: Version 0.9.2 ACPI: PCI Interrupt 0000:00:02.0[A] -> Link [LNKA] -> GSI 11 (level, low) -> IRQ 11 intelfb: 00:02.0: Intel(R) 855GME, aperture size 128MB, stolen memory 8060kB intelfb: Non-CRT device is enabled ( LVDS port ). Disabling mode switching. intelfb: Initial video mode is 1024x768-16@60. intelfb: Changing the video mode is not supported. Console: switching to colour frame buffer device 128x48 Should I try without it? I don't actually need it that much. If you don't need it, don't use it -- fbdev drivers are a pain for drm drivers to deal with as both fbdev and drm want to 'own' the device. drm tries to share, but there may be bugs with that. Nice to know it's currently busted though, we'll leave this bug open until it's fixed.

Nice to know it's currently busted though, > we'll leave this bug open until it's fixed. I tried without intelfb in the kernel and it does seem to work better -- I don't get the oops anymore. Not that it helps that much, as my system still freezes hard when I close glxgears (which I don't even know where to report, as I can't guess if it's a DRM or X.org issue), but still -- it's progress. Thanks. Closing due to inactivity. Reopen if this is still a bug. |
