Hi,

Someone already reported problems with ide-floppy in 2.5.69, but this seems to
be a slightly different issue. I'm not seeing timeouts, but the following
backtrace with an IDE Zip drive (hde) instead. Also strange is that I have
sector 0 read errors on the cdrom (hdf) during bootup.
Looks like it tries to read the partition table from a cdrom without cd.
See below.

-Regards,
