Crash in drm_atomic_helper_wait_for_vblanks on 4.13.x #113

Closed nullr0ute closed 6 years ago

nullr0ute commented 7 years ago

Fedora 27 with 4.13.2, mesa 7.2.0 and gnome 3.26, we get a series of crashes in drm_atomic_helper_wait_for_vblanks during the early boot process while X/wayland/gdm is starting up, and sometimes during use, although I'm not testing using thoroughly atm. There seems to be a couple of variations of the crash so I've included them all.

Going to close this, I think this is actually a false positive from a dual applied patch on the Fedora kernel.

For reference we had pulled in upstream ca39b44 (drm/vc4: Fix OOPSes from trying to cache a partially constructed BO.) fix, suggested by Eric, some time ago, it seems that git quite happily applied it twice, with extraneous patch removed it seems OK now.
