[cc me please]

Hi there,

I recently upgraded my desktop to Debian/buster. Now when I start my
xfce session I can hear the system bell, and my dmesg is filled with
numerous:

[  920.728347] do_IRQ: 0.37 No irq handler for vector

The symptoms seems to be gone using git/master:

3a1d5384b7decbff6519daa9c65a35665e227323

Could someone suggest a method/tool to track down which commit needs
backport to v4.19 (other than a git bisect).

For reference:
* this is bug Debian #932304
* I can boot in recovery mode without any issue. It seems to be
related to an event in single mode

Thanks much,
