Try disabling APIC for now.  Your BIOS has a bug in that it tells us that the 
APIC-routed interrupts are active-hi polarity when in fact they are 
active-low.  Unfortunately it seems that a few BIOSen have this bug. :(  All 
PCI interrupts should be level-triggered active-low polarity.  You can also 
try the following patch:
