My Linux Kernel 2.6.27.2 "cat /proc/interrupts" shows 3 Errors


My Linux Kernel 2.6.27.2 "cat /proc/interrupts"
shows 3 Errors. What could cause this? Can this
be caused by parity errors (I have ECC memory)?
Does this mean that my operating system is unstable?

From the kernel documentation for /proc:
Code:
ERR is incremented in the case of errors in the IO-APIC bus (the bus that
connects the CPUs in a SMP system. This means that an error has been detected,
the IO-APIC automatically retry the transmission, so it should not be a big
problem, but you should read the SMP-FAQ.

O.K. on the SMP error. I am still curious because I only
have one Pentium III cpu (single core). Should I change
the APIC setting in the BIOS?

Note: The ERR count appears to be 3 after IPL and stays
at this number. It does not increase, so I don't worry.
If I change the BIOS setting from "APIC" to "PIC" I then
get 6 ERR instead of 3 ERR. Therefore I leave it at "APIC".
