Package: src:linux
Version: 4.19.28-2
Severity: normal

Dear Maintainer, since an unknown moment possibly in the past several months I'm experiencing constant
90-100% CPU load on one core by a kworker/X:2+events process.

At least versions 4.19+101, 4.19+102, 4.19+104 are affected.

According to /proc/interrupts, an overwhelming amount of interrupts comes from a PCI-E port (IRQ 117):

Hi

This bug was filed for a very old kernel or the bug is old itself
without resolution.

If you can reproduce it with

- the current version in unstable/testing
- the latest kernel from backports

please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.

Regards,
Salvatore
