Comment 309 for bug 1690085

I opened a support case to AMD, and buried in several basic steps (what GPU, etc) was "disable C6 in BIOS".

So, sounds like AMD is definitely aware of the problem since disable C6 was in their first support communication.

I have a 1000 Watt Corsair HX1000i and see the idle hang-ups, so definitely *NOT* a power supply issue.

I wonder if windows users see this issue?

For the RCU fix to work, your distro also has to have kernel support for it (CONFIG_RCU_NOCB_CPU). See this article:
