Hash: SHA1
Search the archives for the subject "APIC Error on CPU 0"
I posted it to the list some months ago.
I get these messages every three minutes on 2.6.7.
On 2.6.7-mm6 I get the messages lets say every hour
once. So it's better, but not completely away.
I can't say if the reason is not a faulty CPU. Maybe,
maybe not. Who knows.
But the point is, that its actually is _better_ in -mm.

40 is Received Illegal Vector
20 is Send Illegal Vector
60 means you're getting both errors at the same time.
Basically it means that the APIC bus messages are malformed.
The cause can be hardware or software, it's difficult to tell.
Try a different kernel, w/o ACPI (acpi=off), w/o ACPI PCI
routing (pci=noacpi), or w/o I/O-APIC (noapic).

Well, I have a machine which produces "APIC error" messages only if the
kernel has been configured with CONFIG_PCI_USE_VECTOR enabled. Without
CONFIG_PCI_USE_VECTOR, I get no APIC errors. The machine has a single
1.7GHz P4 in it, and the kernel has ACPI, APIC and IO-APIC support all
enabled. I can provide more detailed information if needed but it will
take some time since the machine is not connected to any network.

Our kernel was also generated with CONFIG_PCI_USE_VECTOR enabled.
And according to a previuos mail by Mikael Petterson the value
60 related to sending and receiving vectors.
The problem only arises in one of our servers, the only one
with an Intel E7505 chipset. Is this related or pure coincidence?

My machine showing the problem has an Abit TH7II-Raid board with the
Intel 850 chipset.
