5.10.37 introduced a lot of DVFS changes for Armada 37xx from 5.13 kernel.Unfortunately commit: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/drivers/cpufreq/armada-37xx-cpufreq.c?h=v5.10.37&id=a13b110e7c9e0dc2edcc7a19d4255fc88abd83cc This patch actually corrects the things so that 1 or 1.2GHz models would actually get scaled to their native frequency. However, due to a AVS setting voltages too low this will cause random crashes on 1.2GHz models. So, until a new safe for everybody voltage is agreed on lets revert the patch. Fixes: d337731 ("kernel: bump 5.10 to 5.10.37") Signed-off-by: Robert Marko <[email protected]>
This commit was also backported to v5.4.119 and is now in OpenWrt 21.02 branch, we should probably also revbert it there.
@Robert Are you working with upstream Linux to fix this problem upstream too? For now this revert should be fine.
