Errors at system startup.


#1

When you turn on the system, errors pop up:

  • “no IRQ handler for vector”,
  • “Spectre mitigation: LFENCE not serializing, switching to generic retpoline”

The system starts normally. Is there a way to get rid of these errors?


#2

No not really, most the time those kernel messages are superfluous and can be ignored.
My Intel systems have a bunch of them, like 8 or more.
