Sep 29 16:11:32 freebsd3 kernel: fdc0: <floppy drive controller> port 0x3f7,0x3f0-0x3f5 irq 6 drq 2 on acpi0
Sep 29 16:11:32 freebsd3 kernel: fdc0: [FAST]
Sep 29 16:11:32 freebsd3 kernel: fd0: <1440-KB 3.5" drive> on fdc0 drive 0

For phk:

The debug settings show a loop:

Retry line 1054
Too many retries
00 00 00 00 af 10 12 80 57 00

.... at first. This happens for at least the first 30 seconds. I'll need to setup
a serial console to capture the output accurately because the output changes and
some geom debug is output. There is too much for me to transcribe.

Can you suggest a place where debug could be cancelled because the machine gets
very frantic when it's booted? 8-)
