I get the same message on one of my linux systems (stretch):

Pending kernel upgrade!
Running kernel version:
4.9.0-4-686-pae
Diagnostics:
The currently running kernel has an ABI compatible upgrade pending.
This also occurred before the recent upgrade to 4.9.0-4-686-pae.
Other systems with equivalent setups behave normally.
