The other day I just happened across a strange error message from dmesg
while looking for something else. The output was:
[ 8168.931461] Uhhuh. NMI received for unknown reason 3d on CPU 0.
[ 8168.931466] Do you have a strange power saving mode enabled?
[ 8168.931468] Dazed and confused, but trying to continue
I had never heard of NMIs until now, but they appear to be related to
hardware problems, which is unfortunate because this is on a
liquid-damaged laptop that I cleaned and repaired. It did however only
happy when resuming/sleeping, which is sometimes glitchy with this
laptop anyway. I haven't seen it again since.
I'm hoping that this is a one-off weird thing, or just related to
suspend/resume rather than an indicator that my laptop is about to take
the trip to the big recycling centre in the sky.
