Can anyone explain what the interrupt remapping is?
Would turning this feature off in the Linux kernel cause any problems, or bring any benefits?

It's a software capability for rerouting signals sent from peripheral devices.

I believe this feature allows the kernel to replace the remapping tables created by your BIOS (which is also a piece of software), so if you turn it off, I guess it then becomes a question of how well the kernel and the BIOS remapping get along.
