2.4.0 config breaks /dev/fd0* major/minor ?

2.4.0 config breaks /dev/fd0* major/minor ?

[Jeffrey Rose]

Greetings hard working coders,

I recently installed 2.4.0 on a RH 7 box, replacing the stock RH
kernel-hack that came with the CD distro.

All is well, however, I get a wrong major/minor reported when attempting
to mount /dev/fd0 ... I have tried all the fd0* related to a 1.44 disk
in /dev with same message. The default major,minor for my /dev/fd0 is
2,0 (worked before upgrade).

I apologize in advance for submitting his to the kernel list, but if
anyone has a moment to step away from chronic
kernel-hacking-frustration-syndrom ... I would appreciate I tip as to
what and how I may have broken something in my 2.4.0 config and how to
regain access to my floppy drive.

Sincerely thankful,

Jeff

Sounds like it can't find the floppy driver, for whatever reason...

I have seen this message, new with 2.4.0-2mdk
(before I have 2.4.0-0.15mdk)
but only on one PC.
I have 2 PC, with same hardware, same PCMCIA config
The first have mandrake 7.2 Odissey, and the modules
floppy and floppy_cs are loaded, and /mnt/floppy is mounted
The second have mandrake 7.1 Helium, and the modules
fail during init. and I have this message:
'mount: /dev/fd0 has wrong major or minor number'

Problem of compatibility of some library?

Still checking ...

I also want to mention that the physical drive light *does* indicate
partial success at some level of access, but mounting fails due to the
major/minor problem. I am trying to determine if this is a kernel-CONFIG
or a kernel-SPECIFIC problem I have encountered with this 2.4.0 upgrade.

I have copied the files of modutils-2.4.1-1mdk, 
and created 2 sym.links:
# ls -l /lib/modules/2.4.0-2mdk/pcmcia/
total 0
lrwxrwxrwx    1 root     root           29 jan 10 22:09 ds.o -> ../kernel/drivers/pcmcia/ds.o
lrwxrwxrwx    1 root     root           32 jan 17 11:30 floppy.o -> ../kernel/drivers/block/floppy.o
lrwxrwxrwx    1 root     root           35 jan 17 11:30 floppy_cs.o -> ../kernel/drivers/block/floppy_cs.o
and now, it works!

I am not using pcmcia, as this is a desktop with ISDN (Fritz! PCI ISDN
card), but I only get more verbose error messages with the
/dev/fd0CompaQ :

#> mount /dev/fd0CompaQ /mnt/floppy
#> floppy0: sector not found: track 0, head 0, sector 3, size 2
#> floppy0: sector not found: track 0, head 0, sector 3, size 2 
#> end_request: I/O error, dev 02:04 (floppy), sector 2
#> /dev/fd0CompaQ: Input/output error
#> mount: /dev/fd0CompaQ has wrong major or minor number

I will attempt a recompile with floppy as a module (as RH 2.2.16-22 did
... /lib/modules/2.2.16-22/block/ide-floppy.o), and see if
'ide-floppy.o' and the new 2.4.1 modutils will help resolve this problem
(unless my sad Compaq Presario 5000 BIOS IRQ setup is to blame :-(

Cheers,

Jeff
