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.
