Description Juergen Mell 2005-09-17 19:03:50 UTC

When the SAMSUNG floppy drive SFD-321U/EP is connected the kernel will detect 8
new drives (sda ... sdh). Each drive is operable and shows the same data. The
problem exists for all SUSE kernels since 2.4.x. It was once fixed in a late
2.4.x kernel from kernel.org (I did not try any recent vanilla kernels), but
never in a SUSE kernel.

so does it exist in 10.0 or not?

this patch will likely fix it.

Comment 4 Juergen Mell 2005-09-17 23:42:23 UTC

The bug _exists_ in 10.0RC1 (kernel-default 2.6.13-9).
The patch did NOT fix the problem (although I really expected it). Hmmmm. I
modified unusual_devs.h, then did make cloneconfig, make prepare, make modules
and make modules_install. After that rebooted. As all modules are now 'tainted'
I believe the new modules are used. Very strange. Attached are outputs of lsusb
and the relevant part of the syslog.

diff-output to fix SFD-321U

I finally found it: The firmware version of my drive is newer than the version
which was expected in the original patch and thus the drive was not recognized
with the original version. With the above patch everything works as expected.
The diff was made against the original file from
kernel-source-2.6.13-9.i586.rpm

Thanks, I added the fix to our kernels. Since you found out the problem and the fix, could you also please send this one upstream, so it will be fixed in newer kernels automatically? The maintainer's email adress can be found in the file you just modified ;)
