Funnily enough, Drew's original [PATCH] arm64: KVM: Only skip MMIO insn once http://mid.mail-archive.com/20190821195030.2569-1-drjones@redhat.com has been one of the few kvmarm postings that I've even attempted to read. I congratulated Drew off-list on the debugging and the fix. But, I never connected the patch to your report on edk2-devel! http://mid.mail-archive.com/4e8a0c5f50b642538b310a8edd9ce248@huawei.com Makes me wonder what other connections I must be missing all the time. :) Thank you, Drew, for the fix!
