So it looks like someone has already resolved this issue in the latest Free= BSD code, I dont know if it can be backported to 12, it would be nice if it can, but this is good news regardless. For curiosity sake I am still going to test this on bare metal and will be today, depending on the result of that I will report this to QEMU developer= s. --=20 You are receiving this mail because: You are the assignee for the bug.=
