That's odd. Any you are saying that this happens no nova as foc.
Are the "disappearing interrupts" are maybe shared between several
devices ? If yes, you could try with a Genode version before release
12.11 in which we introduced the support for handling shared interrupts
in general. It's just a guess.

I tested it today on another machine, based on a Intel DX58SO
motherboard and a Core i7 CPU. Could not reproduce it here.
