by writing to the floppy drive on my machine. My floppy driver is
compiled as a module and autoloaded by kerneld. (It doesn't matter
whether or not the module is loaded permenantly by modprobe or
autoloaded. I haven't tried it compiled in) My ethernet card is an
AT-1500BT with the Lance chipset.
I generated this particular mess by first running:
dd if=/dev/fd0 of=floppy
which did not produce any errors, and then
dd if=floppy of=/dev/fd0
which generated all of the above messages. The errors only occur when
the floppy is actually being written to physically (light is on).
Playing around in the cache does not cause any problems.
My kernel is:
Linux version 1.3.94 (root@vorlon) (gcc version 2.7.2) #1 Mon Apr 22
16:53:48 CDT 1996
My machine is a Gateway DX-100 VLB (Micronics motherboard ~1993) with
on board IDE and floppy controller - floppies connected here
AT-1500BT
Adaptec 2842A with floppy interface disabled
PAS 16 with SCSI disabled
24 Meg memory
Diamond Viper video card
I'm willing to try other kernels etc if someone requests it.
