Thanks. I tried v6.4-rc6 and hit the following crash. It seems it has been broken since commit 45c7e8af4a5e3f0bea4ac209eea34118dd57ac64 Author: Thomas Bogendoerfer Date: Mon Mar 1 16:29:57 2021 +0100 MIPS: Remove KVM_TE support After removal of the guest part of KVM TE (trap and emulate), also remove the host part. which deletes kvm_mips_commpage_init() and leaves vcpu->arch.cop0 NULL.
