Created attachment 212308 [details] bhyve: Silence ACPI RTC error/warning in Linux guests From dmesg: ACPI Error: Could not enable RealTimeClock event (20180810/evxfevnt-184) ACPI Warning: Could not enable fixed event - RealTimeClock (4) (20180810/evxface-620)
Also, please MFC if possible. Thanks.
I'd held off this until looking at Linux source to make sure there weren't any side-effects, but this doesn't appear to be any worse than the RTC's currently unimplemented calendar alarms, so I'll get this in. Thanks !
