Code:
Message from syslogd@thinkpad at Jan  8 19:31:26 ...
 kernel:[33942.834954] Uhhuh. NMI received for unknown reason 3d on CPU 0.

 kernel:[33942.834972] Do you have a strange power saving mode enabled?

Message from syslogd@thinkpad at Jan  8 19:31:26 ...
 kernel:[33942.834977] Dazed and confused, but trying to continue

Code:
# uname -a
Linux thinkpad 4.3.0-1-amd64 #1 SMP Debian 4.3.3-2 (2015-12-17) x86_64 GNU/Linux

Sorry, this ThinkPad X120e is running Debian Linux (testing) at the moment, but since I normally run Gentoo I thought I’d ask here anyway…

Anyone ever seen this?

The laptop runs normal and stable since then. It must have happened while I was not at the computer and it may be that the display was turned off due to power saving mode. The laptop is on A/C and I have deactivated all suspend settings, so it will run until I turn it off intentionally.

The messages appeared in the windows of an active console, actually a root (user root, via “su”) Konsole of my KDE Plasma desktop.

See if you can replicate the problem in Gentoo. Usually this is a kernel problem. We don't know what Debian puts in their kernels.

If this also happens in Gentoo, likely then you are dealing with a hardware problem or you have some missing driver. Unfortunately NMIs are hard to debug without the original hardware schematics...

If you want to debug Debian, this thread belongs in OTW...

Thanks. I was just wondering if someone else may have seen this before.

It happened again. Maybe I just noticed it or maybe Debian (testing) recently shipped a new kernel. The hardware works normally though, so there are no real disturbing effects (yet).

I would love to get Gentoo onto this box too, but time does not permit it. I am currently trying to get Gentoo running on my Power Mac G5, which is not that easy to accomplish and consumes all the spare time I have available.

Again: thanks. As I said, I was just wondering if these messages have appeared on Gentoo installations as well.
