I don't see anything in the sa1111 core, soc_common, or sa11* pcmcia
code which would cause this change of behaviour. I think it may
require a bisect to find what change broke this.

These are fine - the soc_common code intentionally tries to set the type
to rising, then both edges - the idea being that we get rising edge if
the hardware doesn't support both edges.

And this suggests no interrupts what so ever are coming from the drive.
