VIA 82c686b and IOMega ATAPI ZIP 100 problem

[Stepan Roh]

I'm experiencing serious problems with Linux, VIA vt82c686b IDE interface
(as included on VIA KT133 (latest revisions), KT133A and newer chipsets)
and IOMega ATAPI ZIP 100 drive. Error description and system information
are included below. That is a known problem with this chip. Something bad
happens with ATAPI there (but only for IOMega ATAPI ZIP 100 and some old
CD-ROMs - I have both). Under Windows (which I don't have) you can install
beta version of VIA IDE Busmaster drivers to solve this problem. I wrote
to MSI (manufacturer of motherboard) and to VIA. Guys from VIA did not
replied to me and from MSI they sent me Windows drivers with suggestion to
try it under Linux. Is there any real solution for this problem under
Linux?

I'm not subscribed to this list, so please CC to me.

Thanks,

Error description:

When writing data to IOMega ATAPI ZIP 100 drive, whole IDE interface is
frozen including all programs accessing it. Unmount is impossible (even
when I try to force unmount with SysRq). Following messages are written to
syslog (these messages slightly differ from kernel version to kernel
version (I tried 2.2.18, 2.4.2, 2.4.3) - following is from 2.4.3 when
overwriting large file):

Mar 31 20:26:24 penguin kernel: Filesystem panic (dev 16:44).
Mar 31 20:26:24 penguin kernel:   fat_free: deleting beyond EOF
Mar 31 20:26:24 penguin kernel:   File system has been set read-only
Mar 31 20:27:47 penguin kernel: hdd: lost interrupt
Mar 31 20:27:47 penguin kernel: ide-floppy: CoD != 0 in idefloppy_pc_intr
Mar 31 20:27:47 penguin kernel: ide-floppy: CoD != 0 in idefloppy_pc_intr
Mar 31 20:27:47 penguin kernel: hdd: ATAPI reset complete

Last 4 lines are repeated as long as file is not written (this depends on
file size). On 2.2.18 kernel additional set of messages similar to the one
below is written:

Mar  4 19:50:55 penguin kernel: file_cluster badly computed!!! 0 <> 3315

Writing speed is aprox. 1000 times slower than it was on my old computer.
