This is my first post on this forum so... Hello everyone!

It seems like VirtualBox completely ignores nIEN bit in control register of IDE controller. Interrupts are generated even after setting nIEN bit to 1. Can anyone else confirm this behaviour?
I am using VirtualBox v5.2.4 on Linux host. I've never seen this problem before since it's the first time I am trying to support both DMA and PIO modes at the same time. QEMU and Bochs don't seem to have this issue. I know I can just ignore these out of place interrupts but I wonder if this is VirtualBox bug.
