Adding myself to the list as I see the same problem on a Toshiba Tecra A8:

Seems to start only if the system is put to some load, though (launching Eclipse, VMWare or a database server). Removing the ohci1394 module doesn't help, either: [...] [17183117.352000] APIC error on CPU1: 40(40) [17183117.352000] APIC error on CPU0: 40(40) [17183117.448000] APIC error on CPU1: 40(40) [17183117.448000] APIC error on CPU0: 40(40) [17183131.544000] ieee1394: Node removed: ID:BUS[0-00:1023] GUID[0000390000a62cac] [17183195.636000] APIC error on CPU1: 40(40) [17183195.636000] APIC error on CPU0: 40(40) [17183195.708000] APIC error on CPU1: 40(40) [17183195.708000] APIC error on CPU0: 40(40) [...] I don't know whether this is really causing any trouble or just being an "aesthetic" thing, but I would like to have getting it fixed anyhow. Kernel is 2.6.17-10-generic from Edgy.
