I know a request was made to Canonical to enable the option, and it appears the request is being considered, although the option may be limited to ARM64, depending on how Canonical's evaluation goes. I am not aware of any particular issues, so I cannot say what the side effects are, or what platforms are considered to exhibit such issues. -- Jeffrey Hugo Qualcomm Datacenter Technologies as an affiliate of Qualcomm Technologies, Inc.
