This bug seems to have begun with about 3.19.0-4 It does not seem to be present in 3.16 (But in 3.16 the screen shows in low resolution)
It appears to be related to the nouveau graphics driver, as installing proprietary nvida seems to clear it. Tested with mainline 4.0 The bug does not seem to be present, (made two attempts, in both cases the computer awoke normally) marking as "kernel-fixed-upstream" (But as I have no wifi with the 4.0 kernel, I'll be returning to 3.19 for everyday use. is this a bug or expected?) Marking confirmed as requested. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1445535 Title: Hang and kernel panic on wake up from suspend.
