Kernel Kernel bug caused by (cpufreq: mediatek: Refine mtk_cpufreq_voltage_tracking()) on Banana Pi R64 (MT7622)

[Allen-KH Cheng (程冠勳)]

Hi Nick,

This issue doesn't seem to be going to happen.
Is there anything else we need help confirming?

Thanks,
Allen

Did something changed on master? I compiled now the image I use on the
BPI-R64 a bit differently.
I used the openwrt toolchain "aarch64-openwrt-linux-musl-" to cross-
compile the original linux repository on current master. Than I
compiled with OpenWrt-Buildsystem a initramfs, put that together with
mkimage to a "itb" and booted it. Suddenly it works:
