--- Comment #8 from Bernd Steinhauser <linux at bernd-steinhauser.de> --- I noticed that those two lines coincident with a certain event I can trigger: Switching the DP-0 display off (an Eizo EV2455). This leads to a disconnect of the DP connection and that leads (somehow) to the quoted messages about the failed vblank. (I'm not sure if the disconnect is actually a bug in the kernel (as it's a DP1.2 display) or if it's my hardware/mainboard/gpu too old.) However, this disconnect does not lead straight to the freeze. And so far I haven't seen the bug directly after a DP disconnect, but just at some random point. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
