# vmstat -i
interrupt total rate
fxp0 irq11 1986997576 618
ata-pci0 irq14 43093267 13
ata-pci0 irq15 85069735 26
pn0 irq10 1083789644 337
ahc0 irq9 433666 0
clk irq0 321001949 99
rtc irq8 410878329 127
Total -363703130 -113
The 'total' variable is only a signed long. Could this possibly be changed
to an unsigned long or even a long long?
>How-To-Repeat:
>Fix:
In vmstat.c:
void
dointr()
{
register long *intrcnt, inttotal, uptime;
inttotal should be changed to an unsigned long, if not a larger datatype.
