There is obvious difference in the value of 'After init' 0x01000000 (working case) vs. 0x000e4004 (broken case), and nothing else pops up to me. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1339939 Title: [Lenovo ThinkPad T400] intel graphics fail after suspend with 3.16 kernel Status in The Linux Kernel: Incomplete Status in “linux” package in Ubuntu: Incomplete Bug description: After resuming from suspend, I find gnome-shell has crashed.
