Package: procps
Version: 1:3.2.7-3
Severity: normal
Hi,
with dyntick kernel (2.6.21), vmstat sometimes report 0 interrupt.
This is because with dyntick, timer interrupt are not always interupt 0
(pit) but it can be also apic (counted as local interrypt).
So vmstat should take care of local interrupt (and may be mmi) in its report.
Thanks

OK, so its just reporting what the kernel gives it, closing bug.
