Please explain it a bit more.
For example, Is the output format which you think below (on i386) ?
% vmstat -i
interrupt total rate
isa0 irq 0 10000 100
isa0 irq 11 100 3
de0 100 3
stray 0 0
in the condition given below
pci0 at mainbus0
ppb0 at pci0 ...
pci1 at ppb0 ...
de0 at pci1 ...
de0: interrupting at irq 11
If so, I like mainbus0 rather than isa0, because printing isa0 may
confuse users, and because ICU is not located on ISA bus, but on
