After it's booted, all seems well (except that the DVD drive on hdd drags the UDMA133 HD on hdc down to 24 Mb/s instead of 40 Mb/s like hda).Did DMA ever work without problems on this system, for any previous Red Hat release, with or without my patch?
RH7.3 worked fine (albeit at UATA100 instead of 133) on all stock RH kernels i tried (2.4.18-3 & 2.4.18-10 IIRC). It was only on kernels that added support for the chipset that i had errors.
(I find it very suspicious that only the IDE channel which has two devices on it is having DMA problems. I'd try the same things David suggested: unplug DVD, reposition/replace IDE cable, etc...)
I'm guessing the DVD has something to do with it, since it's only UATA33 capable.
On that note, is there anything i can try under Windoze that would give me a feel for how well the drivers on it are working?
