FWIW, I've also had successful runs with the first three of the split changes, and with all of them.
Ok I've just pushed a branch testing-3.15-v3 to fdo which moves all page table allocation to the end of VRAM. Please try with this memory layout, it should give us a good idea if it's indeed a memory corruption or something else.
That branch just survived piglit as well.
Apart from that please try to lockup your system with radeon.lockup_timeout=0 on the kernel commandline and then try to get a dump of the vm page tables with the script I've send to you in one of the mails.
Any preference for which changes of which branch I should try this with? E.g. with the two overalignment changes from testing-3.15-v2?
