Even stranger, here's part of "systat -vm":

 Interrupts
  418 total
  stray irq0
  stray irq6
  stray irq7
  vx0 irq9
  117 sym0 irq12
  sym1 irq10
  atkbd0 irq
1 fdc0 irq6
   72 isic0 irq1
  sio0 irq4
  sio1 irq3
  100 clk irq0
  128 rtc irq8
 elpt0 irq7

Note that IRQs 0, 6, and 7 are listed twice, once as `stray', and once
belonging to their actual devices.

This is -current as of approximately April 1.

The printer driver bogusly sets up its interrupt for every write(2).
Apparently there are some races in this.

I get strays for 0, 6 and 7 consistently on 2 machines here.  I also get
a stray irq15 on a machine that actually uses irq15 (for ata1).

I think these are caused by the same races at boot time.  They mess up the
systat display.
