I got this crash report when resuming after testing suspend. I didn't notice any problem--suspend and resume went without a hitch. I'm on Lucid Alpha 3 with the latest updates.

I have marked this as a dupliate of bug 525517. This bug has a few differences from the other bugs that are duplicates of that one, but it is sufficiently similar that I would guess it is the same underlying bug. The differences are that most of the others have nothing in the ringbuffer (in IntelGpuDump.txt). and that they have PGTBL_ER: 0x00000010 while this has a little bit in the beginning of the ringbuffer (which has been read by the GPU) andPGTBL_ER: 0x00000001. The PGTBL_ER (page table error) register difference is minimal, since one them indicates a problem in display plane A and the other one the same problem in display plane B.

[Geir Ove Myhr (gomyhr)]

For the record, I wasn't quite right on the display plane A/B issue. It was 0x00000010 and 0x00000100 that are that pair ("Invalid GTT Entry during Display A Fetch" and "Invalid GTT Entry during Display B Fetch"). 0x00000001 means "Invalid GTT Entry during Fetch on behalf of the Host" which is still pretty similar. This information is available in section 8.2.1.2 in http://intellinuxgraphics.org/VOL_1_graphics_core.pdf .
