You're getting a lot of receive and send (checksum and accept) errors and
as a result invalid vectors being sent to your processors, your APIC bus
is seeing a lot of data corruption, looks like your motherboard might be
on it's way out. Try running with 'noapic' to see if it's the IOAPIC or
local APICs (my bet is on the IOAPIC which would be on your motherboard
chipset)
