The device probe for the CMOS RTC chip handles that (I assume) - none of my stuff ever gets called if the device isn't found on the ACPI bus. The reimplementation of the CMOS read/write methods is just to allow ACPI multibyte accesses (the existing read/write calls lock single byte accesses).

And amd64 doesn't matter - works for x86-based computers with the basic CMOS RTC chip (PNP0B00). Hopefully your suspend/resume problems are due to your ACPI BIOS needing to read/write info from/to CMOS and not finding a CMOS handler. >> >> Anthony >> >> On 08/25/2014 11:50, 张晓靖 wrote: >>> I google less than complete information.
