heyjoe:

After running ‘zypper up’ which updated to kernel 4.4.120-45.1 and rebooting I get:


~]: dmesg...
    1.717166] NVRM: loading NVIDIA UNIX x86_64 Kernel Module  390.42  Sat Mar  3 04:10:22 PST 2018 (using threaded interrupts)
    1.719392] Spectre V2 : System may be vulnerable to spectre v2

I saw that on one system. Since it was VM used for testing, I didn’t worry too much.

I noticed that there were more updates. I applied them and rebooted. And I have not seen that message since.

I think it was due to a bad update (probably an incomplete update). There were possibly two packages that needed updating together, and I managed to get in when only one of those was available.
