Comment 261 for bug 1690085

I've seen something new on one of my two affected machines. Note I have C6 *on*, but I'm running stress-ng 24/7 which keeps one core at 100%. The machines have been rock-solid since I started doing that, about 3-4 weeks uptime now.

Anyway, this message came up on one of them:
[1905495.738522] Uhhuh. NMI received for unknown reason 3d on CPU 8.
[1905495.738523] Do you have a strange power saving mode enabled?
[1905495.738524] Dazed and confused, but trying to continue

I have no idea what to make of this, perhaps it can help.
