This is the "famous" A64 timer errata/bug: https://lists.denx.de/pipermail/u-boot/2016-November/271836.html

Currently there are no 100% reliable ways to fix this, and it's not up to us to fix.

Possibly DRAM instability or CPU underpowering. So DVFS tables and DRAM frequency need to be checked first by anyone who wants to investigate and fix this, assuming there are no HW issues.
