If the failues do _not_ come back then the problem is somehow affected/worked-around by the IO-APIC code that generates the above 4 lines. If the failures are still the same then the above 4 lines are really just an uninteresting side-effect of the acpi_use_timer_override flag - and the real side-effects (that fixes PATA on your box) are to be found elsewhere. Sadly, the latter variant is the expected answer.
