https://bugzilla.kernel.org/show_bug.cgi?id=210415 Bug ID: 210415 Summary: [amdgpu] constant GPU hangs followed by kernel "BUG" and following kernel oops Product: Drivers Version: 2.5 Kernel Version: 5.9.11 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: david.alejandro.rubio@xxxxxxxxx Regression: No Created attachment 293863 --> https://bugzilla.kernel.org/attachment.cgi?id=293863&action=edit dmesg output I have an RX 480. Every few hours after kernel 5.4 (!) I've been getting random GPU hangs, and after kernel 5.9, they became not only more frequent, but afterwards the kernel sent messages like Nov 29 15:44:31 reimu kernel: [drm] Bailing on TDR for s_job:34a, as another already in progress Nov 29 15:44:31 reimu kernel: BUG: kernel NULL pointer dereference, address: 0000000000000020 Nov 29 15:44:31 reimu kernel: #PF: supervisor write access in kernel mode Nov 29 15:44:31 reimu kernel: #PF: error_code(0x0002) - not-present page And an Oops right afterwards Oops: 0002 [#2] PREEMPT SMP NOPTI The full dmesg is attached. Kernel is compiled with Archlinux kernel preferences, but using a kernel directly from kernel.org and compiled with the modules I need give me the same error. Attached error. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
