FWIW, I've also had successful runs with the first three of the split

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.
Ok, so it's probably not an alignment issue but indeed a memory
corruption (crap, the former would be easier to fix).
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?
Just a blank 3.15 should be sufficient, I just want to take a look at
the hexdump of the page tables to figure out what kind of memory
corruption we have here.
Thanks,
Christian.
