I have an Asus P4P800-VM system (i865G chipset) and when I plug in a DVD drive (NEC 3520) instead of a CDROM I get the following kernel errors (versions 2.6.9 through 2.6.11-pre4):

If I run with noirqdebug, it just freezes once it displays the _NEC message. I tried disabling APIC but no luck. Any idea what could be causing this problem?
