The theory is that if kldload runs on an A72 core, the passed tcr_el2/vtcr_= el2 values aren't compatible with A53 cores, but it's ok the other way around. One way to see if this is the case would be to pin the kldload onto an A72 core, and then onto an A53 core, and see if it works one way but hangs the other. cpuset -l kldload vmm.ko where cpu-num is the number assigned to an A72 or A53 core. --=20 You are receiving this mail because: You are the assignee for the bug.=
