** Description changed: - My initial bugreport was here: - https://bugs.freedesktop.org/show_bug.cgi?id=71116 + [Impact] + * Relocations on nv04-nv4f are completely broken, any kind of memory stress will result in userspace failure. + + [Test Case] + * Suspend on a system with an affected nvidia card. + * Resume should complete without any errors in FIFO. + * Other test is to run max-texture-size from piglit, system should survive. + * For m-a same change: confirm libdrm-dev:amd64 and libdrm-dev:i386 coinstall. + + [Regression Potential] + * Original bug report was caused by undefined behavior in gcc: + - *push->cur++ = pushbuf_krel(push) + - pushbuf_krel uses (push->cur - push->bgn) to calculate offset. + - It's undefined whether push->cur is incremented before calling pushbuf_krel or not. + - New gcc changed the order, causing the bug. + - Fixed by calling push->cur++ in a separate statement. + * Bug reports will be watched for any new problems that may pop up. + + [Original bug report] + My initial bugreport was here: https://bugs.freedesktop.org/show_bug.cgi?id=71116 - Recompiling libdrm with gcc 4.7 fixed the bug. Upstream GCC mail thread here: http://gcc.gnu.org/ml/gcc- help/2013-07/msg00103.html This was fixed thanks to Emil Velikov from the nouveau project.
