Yes that was wat i meant with another firmware glitch, masking the fact that your fix seems actually ok.

I have seen many issues with the IVRS table regarding IOAPIC. This is the first time I see with the HPET, in which case, your patch simply So, my understanding is the patch still does not solve the issue where the IVRS and HPET table has conflicts here.  This means we should also have the override mechanism for the HPET entry of the IVRS (i.e. the variety 2 as well)?

Nevermind, there is also the kernel option "ivrs_hpet" for that.
