Description of problem:
(This might not be the most appropriate forum to announce this bug, but it
sure would have helped me if this was here when I started looking for the
problem. Apols in advance.)
Problem when writing data to a IDE/Internal ZIP disk from Redhat 7.1
(kernel package version 2.4.2-2 or 2.4.9-6) as well as earlier, kernel
2.2.x based distributions.
When writing any largish (say, over a couple of blocks) files to the zip
drive, a sync or umount /mnt/zip command will hang, and eventually return
kernel error messages. Reads, and smaller writes, appear to work fine.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Run redhat-7.1 on a Athlon system with the Via 82C686B chipset)
2. Mount a IDE Internal ZIP drive
3. Write some data... at least 1MB
4. Umount the ZIP disk
Actual Results: The write will appear to work, but the umount
will 'hang'. The kernel will eventually report these errors:
hdd: lost interrupt
ide-floppy: CoD != 0 in idefloppy_pc_intr
hdd: ATAPI reset complete
If a 'sync' is issued instead, 'sync' will hang in a similar fashion,
including the errors.
Expected Results: Data written and umount (or sync) returns.
After about 2 days research (which is why I'm so keen to tell SOMEONE
about this... don't want all that time wasted). I found that there's a
problem with the Via chipset as used with the Athlon motherboards. I tried
the above on two motherboards with a Athlon 1200MHz and 1400MHz, with the
same error; they used the same chipset. EXactly the same equipment, but
with a intel CPU and motherboard, worked just fine.
Here's an example of a windows user with a similar problem:
And a linux user:
Later IDE knows ab out this so ought to be reliable. If not please re-open
