https://bugzilla.kernel.org/show_bug.cgi?id=211875 Bug ID: 211875 Summary: CPU frequency scaling lost after "WARNING: CPU: 2 PID: 2358578 at smu8_send_msg_to_smc_with_parameter+0xfe/0x140 [amdgpu]" Product: Drivers Version: 2.5 Kernel Version: 5.11 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: erhard_f@xxxxxxxxxxx Regression: No Created attachment 295381 --> https://bugzilla.kernel.org/attachment.cgi?id=295381&action=edit dmesg (kernel 5.11, A10-9700E) I get this on kernel 5.10.17 and it happens on 5.11 too (though a lot less often). Leaving the machine running for some hours sooner or later I get this "smu8_send_msg_to_smc_with_parameter(0x0011, 0x460) timed out after 3234846 us" in kernel dmesg and after that CPU clock frequency is hampered to the 800 MHz base clock of the A10-9700E. Setting cpu manually to performance or back to ondemand does not change a thing, clock stays down at 800 MHz. The machine does not crash and is still usable but well ... slow..
