I am contacting you because your patch "bf22ff45b genirq: Avoid unnecessary
low level irq function calls" broke suspend/resume on an old Intel platform.

This was not caught in linux-next and only got introduced in linux 4.13-rc1.

Here is the current place where the bug has been reported[0] but I can move it
to bugzilla.kernel.org if you would want that.

Can we please handle this per mail?

Sure, if you prefer.


Here are the kernel logs[1]. What information would you need?

Output of 'cat /proc/interrupts' and a description what kind of 'old' Intel
platform that is.

Sorry, I should have repeated the name outside of just the subject of the email. It is an Intel Eagle Lake Core2Duo.
