RedHat has provided a KB (Failure to boot on Red Hat Enterprise Linux (RHEL) 7 or 8 using Hyper-V 2016 - Red Hat Customer Portal), but it is basically useless. They blame Microsoft, fair, but we need a workaround until we can upgrade our Hyper-V hosts.
Has someone found a workaround for this?
This is a fully updated RL 8.10 with kernel 4.18.0-553.8.1.el8_10.x86_64.
