Thanks, it scheds some light on the issue. See below.

This is dump of the IVRS table contents. It tells us that IOAPIC with ID
5 uses PCI request-id 00:00.0. But this information is wrong, it uses
request-id 00:00.1, as seen below:

This message comes from an interrupt request sent by the IOAPIC, and it
uses a different request-id. Can you try to update the BIOS on that
machine and test if it fixes the issue?
