As far as I can tell from the history here, CONFIG_HARDENED_USERCOPY_PAGESPAN was responsible for the desktop not coming up. Having the "rewind the stack before do_exit()" patch in combination with that option prevented booting, becuase the usercopy hardening created an oops that triggered the code paths affected by the patch (but I'm still not sure what about that patch caused boot to hang). -- 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/1627198 Title: 4.8.0 kernels do not complete boot process on VM Status in Linux: Unknown Status in linux package in Ubuntu: Fix Committed Status in linux-raspi2 package in Ubuntu: Fix Committed Status in linux source package in Yakkety: Fix Committed Status in linux-raspi2 source package in Yakkety: Fix Committed Bug description: On my native amd64 box, 4.8.0-15 works just fine, but on my VMWare Fusion 8.5 system, none of the 4.8.0 kernels complete the boot process. I tried 4.8.0-15 from yakkety and 4.8.0-16 from yakkety- proposed. Currently I am seeing the last message in my console at boot up as: [ OK ] Started Bluetooth service and then... it just sits there. Through the use of snapshots, restores, and package bisects, I've definitively narrowed it to linux-generic linux-image-generic and linux-headers-generic.
