FreeBSD base system does not provide an ACPI handler for the PC/AT RTC/CMOS device with PnP ID PNP0B00; on recent HP Envy laptops, the absence of this handler causes suspend/resume and poweroff(8) to hang/fail, emitting e.g. ACPI Error: No handler for Region [RCM0] (0xfffff80005796480) [SystemCMOS] (20150818/evregion-176) ACPI Error: Region SystemCMOS (ID=3D5) has no handler (20150818/exfldio-317) These HP laptops have BIOSes which attempt to query the RTC date/time regis= ters via ACPI before suspending/powering off. ACPI-5.0 specification section 9.15 describes the ACPI interface to the RTC/CMOS device (atrtc(4) in FreeBSD). I have implemented this ACPI handler; adding this allows poweroff and suspend/resume to occur. At a FreeBSD committer's request, I've also implemented the same patch with additional changes to atrtc(4) to separate = the bus functionality from the core functionality. --=20 You are receiving this mail because: You are on the CC list for the bug.=
