I'm having a problem with the new VIA IDE controller.
It initializes my drives correctly, then proceeds to start up the operating
system, gets to about crond, then the drive halts for about 30 seconds with its
light on solid. After 30 seconds, it says DMA timed out and disables DMA.
This does not happen on 2.4.0-test7, and DMA works like a charm.
Here's a boot log starting with IDE (and me hitting Alt+SysRq a couple of times):

With the old VIA driver, it did this:

and functioned pretty much normally.
Any ideas?
