this is the problem in OM Cooker and possibly ROME, these commands are run in sequence:
$ sudo rmmod kvm_amd 2>/dev/null
[sudo] password for ben79:
$ lsmod | grep kvm_amd
kvm_amd 217088 1
kvm 1302528 3 kvm_amd
ccp 172032 2 i2c_designware_platform,kvm_amd
There is something preventing rmmod from removing these modules.
