VIA IDE bug with WD drive?

VIA IDE bug with WD drive?

[Karnik, Rahul]

Hi all,

I get the following error if I try to enable DMA on my Abit KT7 motherboard
with a VIA2C686 chipset:

hdb: irq timeout: status=0x58 { DriveReady SeekComplete DataRequest }
hdb: timeout waiting for DMA
hda: DMA disabled
hdb: DMA disabled
ide0: reset: success

hdb is a Western Digital 136BA 13,6 GB drive and hda is a Maxtor 20GB drive.
I do not get the error when enabling DMA on the Maxtor drive (hda).

I have tried kernel versions 2.2.16-3 (stock RH7), 2.2.17 and 2.4.0-testx.
Is this a known bug? Is it solved by the IDE backport patch?

TIA,
Rahul

i get the same thing, along with a crc error, over and over on a 
20-gig WD IDE drive. alternately puzzling and frightening. 
apparently, wd uses some nonstandard goofball error checking thing 
that just doesn't work with linux at present. it *seems* to do no 
harm.

Ok, both of you, we can try to track this down.

1) Please try with 2.4.0-latest. 
2) Send me the complete dmesg.
3) Send me lspci -vvvxxx
4) Send me /proc/ide/via

I'll see what I can do about the driver.
