Previously, in kernel 3.12.21-r1-gentoo, I had the same problem (the screen is sometimes messy after hibernation, and the same "fence wait failed" error in syslog). Before that, I ran deblobbed kernels 3.8.13-gentoo and 3.4.9-gentoo, and there were also problems with the screen, but a bit different. The screen just became black (sometimes it happened after hibernation, sometimes just during the normal work), but the mouse pointer was there, and the error in syslog was different: it started with "kernel BUG" at some location. I don't have the syslog from 3.8.13, but in 3.4.9 it was at mm/slub.c:3474 . On my system, both problems (the one I have now and the one I had previously) happen rather irregularly. -- You are receiving this mail because: You are watching the assignee of the bug.
