Hello everyone.

I tried 2.6.32-rc6 with my Dell Inspiron 1525, but the KDM didnt
display right - It was mostly black with only the cursor displayed.
Other things which use X dont work with the kernel, too.

dmesg shows the following:

i915: Waking up sleeping processes
[drm:i915_wait_request] *ERROR* i915_wait_request returns -5 (awaiting 5 at 3)

After bisecting i got to the following commit:

176616814d700f19914d8509d9f65dec51a6ebf7 is the first bad commit

    intel_agp: Use PCI DMA API correctly on chipsets new enough to have IOMMU

    When graphics dma remapping engine is active, we must fill
    gart table with dma address from dmar engine, as now graphics
    device access to graphics memory must go through dma remapping
    table to get real physical address.

    Add this support to all drivers which use intel_i915_insert_entries()

If you have any more questions, feel free to ask. (CC'ing would be a
good idea ;) )


Thanks everyone for the work for linux so far,

Michael
