A user reported [1] that the Realtek ethernet r8169 stops working after S3

My desktop also has this device, which is also affected by this regression. So
I did a bisect, and this is the bad commit:
bc976233a872 genirq/msi x86/vector: Prevent reservation mode for non maskable
MSI
After this commit gets reverted, the issue is gone.
Sigh. Can you please apply the debug patch below and provide the output of
# cat /proc/interrupts
and full dmesg after resume.
Thanks,
