Innocuous-looking one-liner is said to have made Milan's X server even worse than normal.
Summary: [i915] Framebuffer ID error after suspend/hibernate leading to X crash Product: Drivers Version: 2.5 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: Video(DRI - Intel) AssignedTo: drivers_video-dri-intel@kernel-bugs.osdl.org ReportedBy: nalimilan@club.fr CC: chris@chris-wilson.co.uk Regression: YesI've been experiencing X freezes and crashes for more than a year, and with every kernel version the cause of the bug changes. After Linus pushed 985b823b919273fe1327d56d2196b4f92e5d0fae to 2.6.35rc6 (see below [2]), I'm now getting an "invalid framebuffer id" error that kills my X server. Before that commit, I was getting an oops, which was reported in bugs.fd.o as [1].

drm/i915: fix hibernation since i915 self-reclaim fixes Since commit 4bdadb9785696439c6e2b3efe34aa76df1149c83 ("drm/i915: Selectively enable self-reclaim"), we've been passing GFP_MOVABLE to the i915 page allocator where we weren't before due to some over-eager removal of the page mapping gfp_flags games the code used to play. This caused hibernate on Intel hardware to result in a lot of memory corruptions on resume.
