In this case the kernel is the "messenger" for the page fault. This is more likely to be a mesa or application issue than a kernel issue.
Can you please raise a ticket to the upstream mesa bug tracker? https://gitlab.freedesktop.org/mesa/mesa/ ** Also affects: mesa (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/2037672 Title: amdgpu: [gfxhub] page fault when switching a video to or from fullscreen Status in linux package in Ubuntu: Confirmed Status in mesa package in Ubuntu: New Bug description: Hi, Switching a video to or from fullscreen freezes the screen for around 10 seconds. This happens with Totem as well as VLC so its not related to a specific app. Additional observations: - The issue seems to be connected to the video's bitrate. With low bitrate videos I cannot trigger the freeze. However, videos with high bandwidth trigger the freeze reliably.
