1. Parallel Port Zip Drives and Kernel 2.2.0

2. Use of the Iomega Parallel Port zip drives crashed constantly whenever
reading files from the zip disk. If the errors continue, the zip drive is
no longer detected, and a reboot will be necessary to use it again.
Errors are similiar to:
SCSI disk error : host 0 channel 0 id 6 lun 0 return code = 27010000
scsidisk I/O error: dev 08:04, sector 21604

This error does not seem to affect writing to the zip disk, and is not
related to bad sectors. This error was first noticed with 2.2.0pre9, and
was blamed on not compiling CONFIG_SCSI_IZIP_EPP16 and
CONFIG_SCSI_IZIP_SLOW_CTR into the kernel. With 2.2.0, these were
compiled in statically, and still no change.

3. Parallel port, zip drive

4. Linux version 2.2.0 (root@shiva) (gcc version 2.7.2.2) #3 Wed Jan 27
00:29:25 GMT 1999

5. No Oops Information

6. This can be triggered, easily, by copying any file of large
size(approximately 5-10 megs, if not large).

I have also heard of other reports of this happening, and one
other user who, after upgrading from 2.0.36, is unable to use his printer.
