2.6.23.9: x86_64: floppy not working: p35 chipset

2.6.23.9: x86_64: floppy not working: p35 chipset

[Justin Piszcz]

Trying to format a floppy (2-3 of them) on a GA-P35-DS4 2.0 with a regular 
Sony floppy on Debian x86_64 with kernel 2.6.23.9:

# fdformat /dev/fd0
Could not determine current format type: No such device
# mformat a:
mformat: Could not get geometry of device (No such device)
#

# cat /proc/interrupts |grep floppy
   6:         38         37         39         41   IO-APIC-edge      floppy

# dmesg|grep -A1 fd0
[   52.689487] Floppy drive(s): fd0 is 1.44M
[   52.704661] FDC 0 is a post-1991 82077

During the 'attempted format'

[34324.175770] floppy0: probe failed...
[34324.575342] floppy0: probe failed...
[34324.974733] floppy0: probe failed...

[34330.168197] floppy0: probe failed...
[34330.168257] end_request: I/O error, dev fd0, sector 0

I've tried a few different floppies, the result is the same.  The system 
is 64-bit only, no 32-bit emulation is enabled using a strict 64-bit-only 
userland.  Has anyone else gotten their floppy drive to work under 64-bit?

Is this just a case of a DOA floppy drive or is something else wrong?

Justin.

Maybe booting from a 32 bit live CD would help determine that. It 
certainly was seen at boot time. Didn't get hooked to some SCSI device 
name by udev, did it?

Retried with some other floppies and later tried the original, everything 
seems to be working now, must have been a bad floppy/some transient issue.

Great! I did test that FC8 with a Fedora kernel will see and use the 
floppy. Even found a floppy to use. Now I have to figure out why I have 
a floppy with a gzipped ext2 filesystem on it. :-(
Doesn't appear to be bootable, I thought it might be SYSLINUX for an old 
system which couldn't boot from CD or USB, but that doesn't seem to be 
the case.

Anyway, glad the problem went away.
