https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=268276 --- Comment #2 from Austin Shafer <email@example.com> --- I don't think it's directly affecting the GPU per se, but instead is causing something wacky to happen with the PCI bus. Then the GPU can't be found on the bus, so the nvidia driver bails and the screen stays black. The GPU fans fully spin up, so it's not like the GPU doesn't have power. Thanks, saving CPU makes sense, polling on resume is an interesting idea. I wonder if not polling makes us do something different that causes us to miss an interrupt or something. It's hard to know without having more info, but I'm not sure what I should do to get better data? --- Also I feel like I should mention this (probably unrelated) issue: https://github.com/amshafer/nvidia-driver/issues/1 This predates commit 9e007a88d65b and therefore has a different root cause, but I'm linking it because the symptoms are the same. In that case it looked like ACPI/buggy firmware, but I find it interesting as a second data point. Maybe the atkbd polling causes us or the firmware to hit a situation like this for some reason. -- You are receiving this mail because: You are the assignee for the bug.
