How about something like the completely untested attached patch?

IMNHO, it improves on what was posted here because it draws a parallel with an AMD erratum and also avoids writes to APIC_TMICT that would get ignored anyway.

Thanks a lot for the rewrite. The patch looks great to me.

I will test it on our test boxes to make sure skipping the APIC_TMICT write in TSC deadline mode does not bring unexpected impact to the old machines.

thanks, rui
