May be for all motherboards, but at least for listed below: ASUS A7V600 TYAN S2466N SuperMicro P4DPE ASUS P2B-DS >Description: If BIOS of a motherboard is set for suspend/stand-by mode when system is idle for a certain time, system will go into stand-by or suspend mode. I do not remember 4.8-R or earlier has problem on the system clock. But system clock is off when system is in suspend mode in 4.9-R and 5.2-R. After wake up, system did not syn its clock with the RTC. Two ways to correct system clock: use date command to update the time manually reboot the system (this means RTC is still correct) >How-To-Repeat: Try to enable "suspend mode" in power management in BIOS. >Fix: When system is suspended, only keyboard can wake it up by default. Maybe some motherborad can be waked up by LAN. I do not know if system can detect a wake up signal. If so, it should check if system clock is off from RTC. >Release-Note: >Audit-Trail: >Unformatted:
