pci=noioapicquirk fixes it.
As mentioned in the patch originally:

https://patchwork.kernel.org/project/linux-pci/patch/20200214213313.66622-3-
sean.v.kelley@linux.intel.com/

+The config option X86_REROUTE_FOR_BROKEN_BOOT_IRQS exists to enable
+(or disable) the redirection of the interrupt handler to the PCH interrupt
+line. The option can be overridden by either pci=ioapicreroute or
+pci=noioapicreroute.[3]

In the absence of the ability to convert your out-of-tree driver for this
hardware to MSI, then can you give pci=noioapicreroute a try?
Sorry, full of typos today.  I'm wondering if you could give pci=ioapicreroute
a try.

I no longer work at Intel but am happy to help try to resolve your issue as
best I can.

Best regards,

Sean
