I haven't been following this thread closely. So, pardon me if I'm
going over old ground. My ASUS A7V333 mobo has a similar IDE
controller...
00:11.1 IDE interface: VIA Technologies, Inc. Bus Master IDE (rev 06) (prog-if 8a
[Master SecP PriP])
Subsystem: Asustek Computer, Inc.: Unknown device 808c
Flags: bus master, medium devsel, latency 32
I/O ports at a000 [size=16]
Capabilities: [c0] Power Management version 2
It's works well at fairly low latencies. But, to get that working, I
had to upgrade my kernel to 2.4.19. The 2.4.18 (and earlier) IDE
device driver unable to do DMA with this chip. Fixing that made a
dramatic improvement in disk performance.
Have you already gone through all the hdparms rigamarole?

This sounds
like an interrupt problem, or else a bad set of hard disk
device drivers. If you sound card want to interrupt, it should get
serviced even if the hard disk was on the bus. Possibly the DMA
controller in this ATA chipset isn't very efficient....
this is sounding expensive...
surely others in the LL audio world are using the "IDE interface: VIA
Technologies, Inc. VT82C586/B/686A/B PIPC Bus Master IDE (rev 06)" - has
anyone anything good/bad to say about this (BTW: i did enable all the 'fix
borken VIA' stuff in the kernel options).
