It will take awhile to see where the vxWorks kernel might be attempting the register 3 operation on ioapic. But since this works just fine when I run the vxWorks kernel directly on HW, I am not inclined to believe there is a big problem with the ioapic driver.
On Xen, as well as real hardware, you will read 0xffffffff from that
attempted access. Xen is merely also making a note that you have a
buggy ioapic driver. My point was that, given you definitely have a
buggy ioapic driver, are you certain you have no bugs in your lapic driver?
