This is getting as weird as it would get :)

It seems that the revert has actually solved the issue reported with 
QCN9074.

https://bugzilla.kernel.org/show_bug.cgi?id=217536

We were trying to reproduce the problem on X86+QCN9074 (with threaded 
NAPI) from quite some time, but there is no repro yet.

Actually, enabling/disabling threaded NAPI is a simple affair; I'm 
wondering to hear that interrupts are blocked due  to not having 
threaded NAPI.

What is the chip that Lenovo Thinkpad X13s is having?
