Hi,

The ide-floppy driver in 2.5.70 and 2.5.70-bk13 seems to be badly broken. I'm
using it with a Zip drive. When booting with a zip disk in the drive, I get:

ide-floppy driver 0.99.newide
hde: 98304kB, 196608 blocks, 512 sector size
hde: 98304kB, 96/64/32 CHS, 4096 kBps, 512 sector size, 2941 rpm
 hde: hde1
 hde: hde1

When actually trying to access files on the zip drive's ext2 filesystem
I get the following Oops:
