I tried 3.2 and 3.3. Although the spurious interrupts were always there, they occurred with frequency lower by a magnitude (15 vs. 300 after X starts). So I bisected that and it lead to a commit which fixes bad tiling for me: http://cgit.freedesktop.org/~ickle/linux-2.6/commit/?h=for-jiri&id=79710...
Pipelined fencing is pretty much just broken and we'll completely rip it out in 3.5. Does this also happen with 3.4-rc2?
Does INTx- stay that way? Or does it frequently read INTx+ if you sample it a lot? If it stays as INTx-, then something other than the GPU is getting stuck (though it's possible this could be related to pipelined fencing, if the fences are programmed to point at some funky memory space).
