I think that's a bug in dma-buf fixed with this patch: https://cgit.freedesktop.org/drm/drm-misc/commit/?id=7fbd0782bf94d46993a7e5c08c0feda8dcab1f76 FWIW that patch fixes the mentioned stacktrace for me. Seems like the patch is only enqueued for drm-misc-next, shouldn't this be in drm-misc-fixes? Christian was going to commit it to the fixes branch as well. This patch is already on the fixes branch for a while. -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.

Created attachment 145698 [details] dmesg log with kernel 5.4-rc2 that shows the null pointer dereference While running the Vulkan CTS, I encountered the following: Running the cases dEQP-VK.memory.allocation.* will trigger a kernel NULL pointer dereference in amdgpu on 5.4-rc2, see the attached dmesg log. After this happens, the GPU can hang too, but doesn't always hang. Hardware: AMD Radeon RX 5700XT (reference card, made by Sapphire) Dell U2718Q (two of them: one through HDMI, other through DisplayPort) AMD Ryzen 7 3700X MSI B450i Software: Fedora Workstation 31 x86_64 LLVM 9 Mesa master (what will be 19.3)
