No. your work round is very risk by merely jumping off the panic check. It will push the whole system into unstable situation if the timer interrupt is not guaranteed to route through the interrupt remapping when interrupt remapping is actually enabled.
The source id checking in interrupt remapping enable the incoming interrupt resource validation, but some platform or chipset have issue for this feature, so we need the kernel adding a option to ensure user to disable it on the issued platform.
source id only a small feature in interrupt remapping, so it is no good choice to disable whole interrupt remapping.
So I suggestion to backport the "nosid" kernel option, tell end user or by dmidecode to backlist this feature on the target platform.
Thanks
