[Bug 535454] Re: [i915gm] GPU lockup 4e55afd6915bf5224263b79e5550b6a4
*** This bug is a duplicate of bug 525517 ***

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.
