This has been fixed in Mainline with "CONFIG_SUN50I_ERRATUM_UNKNOWN1=y" as well as in DT with " allwinner,erratum-unknown1;" in timer node.
As of today the kernel in Buster includes the fix.
Code:
dmesg | grep erratum
[ 0.000000] CPU features: enabling workaround for ARM erratum 843419
[ 0.000000] CPU features: enabling workaround for ARM erratum 845719
[ 0.000000] arch_timer: Enabling global workaround for Allwinner erratum UNKNOWN1

You need to have at least linux-image-4.19.0-5-arm64, version 4.19.37-3 (based on Linux mainline 4.19.37).
