Revert the patches that were fixing the probing of interrupts due
to reports of interrupt stroms on some systems
Can you explain how reverting is going to fix the issue?


The reverts fix 'the interrupt storm issue' that they are causing on some systems but don't fix the issue with the interrupt mode not being used. I was hoping Jerry would get access to a system faster but this didn't seem to be the case. So sending these patches seemed the better solution than leaving 5.4.x with the problem but going back to when it worked 'better.'


I finally heard back from IT support, and unfortunately they don't
have any T490s systems to give out on temp loan. So I can only send
patched kernels to the end user that had the problem.



This is wrong way to move forward. The root cause must be identified
first and then decide actions like always in any situation.
