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