Comment 434 for bug 1690085

I am happy to report 45 days of continuous uptime with "typical current idle" selected in bios, and otherwise vanilla everything including 4.15.0 kernel. My system configuration is as posted above.

I find myself willing to believe the AMD "indirectly" statement: this is related to power supply. My power supply is an EVGA 650GQ, with eco switch set on to reduce fan noise. I suspect that if I swapped it for some other power supply, perhaps one not quite so efficient, or flipped to eco switch off, that I would find myself among those lucky users able to run with default bios settings and 4 watts less power consumption at idle. Unless anybody can refute this theory, I would consider it advisable to post power supply details for anybody still hitting problems.

I suspect that the truth is, some power supplies just do not expect such low full system power draw, and freak out about it. Without "typical current", mine is 38 watts at the wall including 32GB of memory, but unfortunately, only lives a few days at that setting.
