https://bugzilla.kernel.org/show_bug.cgi?id=204145 Bug ID: 204145 Summary: amdgpu video playback causes host to hard reset (checkstop) on POWER9 with RX 580 Product: Drivers Version: 2.5 Kernel Version: 5.1.15 Hardware: PPC-64 OS: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: shawn@xxxxxxxxxx Regression: No Created attachment 283635 --> https://bugzilla.kernel.org/attachment.cgi?id=283635&action=edit 5.1.15 kconfig On recent kernels (at least since 5.1.15), video playback will (sometimes) hard reset my POWER9 system with an AMD RX 580. Due to the nature of the crash, it does not seem that any kernel logs are produced by the event. The system Hostboot firmware does record the crash though, and it produces a GUARD event which disables the CPU slice the crash occurred on for subsequent boots until it is cleared. An upstream Hostboot issue has been submitted by another person who has encountered this behavior as well: https://github.com/open-power/hostboot/issues/180 I have been unable to reproduce the issue on kernel 5.0.9, indicating a regression somewhere in between. Attached is my 5.1.15 kernel config, the output of lspci -vv, and the contents of /proc/cpuinfo. -- 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
