Hi Justin, Ok i enabled the second IOAPIC on my system which didn't make a difference really apart from changing the IRQ assignments. However booting the same SMP kernel with maxcpus=1 (IRQ assignments remains the same and devices are serviced by IOAPIC) i can't reproduce the oopses. Here is one w/o maxcpus... The reason why noapic worked before is because only one cpu was servicing interrupts, however we are serialized per irq line...
