    I've noticed the following errors show up through syslog whenever
there is floppy disk activity:

Apr  1 01:25:51 aries /kernel: stray irq 7
Apr  1 01:27:13 aries /kernel: stray irq 7
Apr  1 01:28:07 aries last message repeated 3 times
Apr  1 01:28:07 aries /kernel: too many stray irq 7's; not logging any more

    I don't think I have anything on IRQ 7.  The closest thing is the
floppy drive controller, which is on IRQ 6:

Mar 21 18:07:06 aries /kernel: fdc0 at 0x3f0-0x3f7 irq 6 drq 2 on isa
Mar 21 18:07:06 aries /kernel: fdc0: (NEC 72065B) [0: fd0: 1.44MB 3.5in] 

    This is with the current 950322 snapshot on an ASUS PVI-486AP4
motherboard with only the 3.5" drive connected.  I was formatting a
few floppies when the stray IRQ messages popped up.

    BTW, someone mentioned that formatting a floppy in FreeBSD causes
a jerky response while doing anything else.  I was successfully
playing two Quicktime movies concurrently with xanim 2.69.7.6 at full
speed without any noticeable jerkiness while fdformat churned away on
a 3.5".
