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..
