[opensuse] Dazed and confused (kernel)
I get this funny error message in both my laptops running Leap 15 some times after they wake up from hibernation: Message from syslogd@ronaldinho at Nov 13 19:59:17 ... kernel:[766544.994402] Uhhuh. NMI received for unknown reason 2c on CPU 0. kernel:[766544.994404] Do you have a strange power saving mode enabled? kernel:[766544.994405] Dazed and confused, but trying to continue I don't know what qualifies as strange power saving mode. I use hybrid suspend, when closing the lid, but this error also happens when I hibernate manually and it does not happen every time. The kernel behaves perfectly well otherwise, despite being dazed and confused. Has anyone seen this and should I worry about it or report a bug?

Yes, I have seen it for years, on my two laptops.

Seems like there's a Led Zeppelin fan among the kernel hackers. ;-) Have a nice day, Berny -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Yes, I occasionally see it after resuming from hibernation or suspend-to-RAM. I haven't found yet any consequence of it, and the laptop suspends and resumes flawlessly for months. -- Regards, Peter -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Thank you all for the reassurance. And 3 cheers to the kernel developers that write funny error messages (when they are not important).

I see crashes or problems relatively soon after the messages. Relatively: one or two days. I have no proof that the messages are related or not. Just a suspicion. -- Cheers / Saludos, Carlos E. R. (from 42.3 x86_64 "Malachite" at Telcontar)
