What does this mean, should I do anything about it? Is tiling nice to have? It sounds like GEM broke something - though maybe it just added a more verbose error report. System: EeePC 701 Kernel: v2.6.36-rc1-5-g23cf24c Chipset: Intel mobile 915G-something Regretably necessary kernel boot option: noapic [ 1.438441] Linux agpgart interface v0.103 [ 1.438441] agpgart-intel 0000:00:00.0: Intel 915GM Chipset [ 1.438441] agpgart-intel 0000:00:00.0: detected 7932K stolen memory [ 1.443353] agpgart-intel 0000:00:00.0: AGP aperture is 256M @ 0xd0000000 [ 1.443353] [drm] Initialized drm 1.1.0 20060810 [ 1.443353] pci 0000:00:02.0: PCI INT A -> Link[LNKA] -> GSI 5 (level, low) -> IRQ 5 [ 1.443353] pci 0000:00:02.0: setting latency timer to 64 [ 1.443353] [drm:i915_gem_detect_bit_6_swizzle] *ERROR* Couldn't read from MCHBAR. Disabling tiling. [ 1.443353] [drm:i915_driver_load] *ERROR* failed to enable MSI I expect noapic explains the MSI failure. I can boot without noapic if necessary for testing, but I can't run with it because I get nasty hangs & reboots. I don't see why that merits an *ERROR*... anyway, what I'm interested in is the "Disabling tiling".
