Nothing overlapped (I verified with "devinfo -u"), but your mail
made me think. I keep my /boot/device.hints on this notebook
identical to GENERIC.hints. After commenting out "fdc" lines
in /boot/device.hints:
$ diff -u /sys/i386/conf/GENERIC.hints /boot/device.hints

I got this:
$ dmesg |grep fdc
fdc0: ic_type 90 part_id 73
fdc0: <Enhanced floppy controller> at port 0x3f7,0x3f0-0x3f5 irq 6 drq 2 on isa0
fdc0: ic_type 90 part_id 73
fd0: <1440-KB 3.5" drive> on fdc0 drive 0
The following now works:
1. "kldload fdc"
2. "kldunload fdc" says "Operation not supported".
3. Kernel compiled with "device fdc".
All results in a working floppy.
The following still doesn't work:
"kldload fdc" on a kernel compiled with "device fdc" results in a panic.
P.S. If I comment out two "ppc" lines in /boot/device.hints, the ppc0
attaches normally, and there's no phantom ppc1.
Cheers,
