I disagree.

I believe the register in question only mirrors the current state of
the interrupt signal. Such registers can be found also in other
bridges.

This register bit is read-only and is set only by hardware.

It should become 1 again when the card is delivering interrupts.

Something is wrong with the setup, causing it to not run.

You could always bisect between working and non-working kernels to
find the commit which breaks the support.
