And the root-cause is that the IRQ info(polarity&trigger mode) provided in MP table in some platforms is not always trusted, and system should re-programme it according to the info parsed from ACPI. If the platform provide correct info in MP table, the issue should be gone. Attached a proposed patch, could you have a try to see whether it can fix your issue.
The outcome is exactly the same than
<20100316182053.GA2258@wavehammer.waldi.eu.org>. However it still
