First off, I've upgraded to Fedora 19 and kernel-3.10.3-300.fc19.x86_64. That in itself had no effect on the bug, good or bad. (In reply to comment #19) > does this patch help: > http://cgit.freedesktop.org/~agd5f/linux/commit/?h=drm-fixes-3. > 11&id=dffd4b65ca8989acb914da3c685c798ca5fcf99c I also had to apply these two: http://cgit.freedesktop.org/~agd5f/linux/commit/?h=drm-fixes-3.11&id=7d61d835824f73dc4097b51f800382467c8049c5 http://cgit.freedesktop.org/~agd5f/linux/commit/?h=drm-fixes-3.11&id=9509f9a174b39db215edf7752de4847eaaca2775 Unfortunately the problem remains. =/
