From: Jarkko Sakkinen <jarkko@xxxxxxxxxxx> A quirk for fixing the committed TCB version, when upgrading from a firmware version earlier than 1.50. This is a known issue, and the documented workaround is to load the firmware twice. Currently, this issue requires the following workaround: sudo modprobe -r kvm_amd sudo modprobe -r ccp sudo modprobe ccp sudo modprobe kvm_amd Implement this workaround inside kernel by checking whether the API version is less than 1.50, and if so, download the firmware twice. This addresses the TCB version issue.
