You spot it:

glutamine# vmstat -iv
interrupt           total rate
TLB shootdown       13595    0
cpu0 timer        3312564   99
ioapic0 pin 9   282417042 8525
msi0 vec 0            320    0
msi1 vec 0          21315    0
msi2 vec 0              0    0
msix3 vec 0             0    0
msi4 vec 0              0    0
