From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows 98) 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): How reproducible: Always 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. Additional info: 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: http://guru3d.com/forum/read_msg.php?tid=222&forumid=cpuamd And a linux user: http://lists.insecure.org/linux-kernel/2001/May/1859.html
Later IDE knows ab out this so ought to be reliable. If not please re-open
