Hi,
the ide-floppy driver (0.98a) produces oops + hang (easy
reproducable) with 2.5.2 (and onwards). doesn't matter if module or
in-kernel. Here's the info when 'using' as module:
taco@brood:~$ cat /proc/version
Linux version 2.5.3-K0 (root@brood) (gcc version 2.95.4 20011002 (Debian prerelease)) #1 Fri Feb 1 12:36:54 CET 2002
here's the output from ksymoops:

If some fields are empty or look unusual you may have an old version.
Compare to the current minimal requirements in Documentation/Changes.

if there's any more info you need to figure this one out or patches for me
to test, just let me know...
Cheers,
Taco.
I'll take a look at it.

One hint is that this bug is triggered when you attempt to add a request
in from of one that has already been started. In case of ide,
ide_do_drive_cmd with ide_preempt would trigger this. That may or may
not be a bug, depends on if the driver knows what it is doing or not.
If the driver knows what it is doing, then this patch should cure your
problem.

when using this in vanilla 2.5.3 it continues to oops.
But, when using Ingo's K0 on top of 2.5.3 it 'works' with this patch.
That is: it doesn't oops.
it now just goes:
brood:~# insmod ide-floppy
using /lib/modules/2.5.3-K0/kernel/drivers/ide/ide-floppy.o
ide-floppy driver 0.98a
hdd: 98304kB, 196608 blocks, 512 sector size
and doesn't return to the prompt
and /proc/modules has
ide-floppy 11744 (initializing)
(even after waiting a _LONG_ time....)
Cheers,
Taco.
