Last modified: 2007-11-30 17:07:24 EST
Description of problem:
the ATI Xpress chipsets aren't recognized by the ide kernel subsystem so dma
doesn't work and performance suffers horribly.
Version-Release number of selected component (if applicable):
install on a board that has the ATI chipsset. for example, the Intel D101Ggc
Steps to Reproduce:
1. install os
3. note that dma is not enabled and performance is quite poor.
no dma for ide disks.

there is a patch at:
that i have tested with both i386 and x86_64 kernels and both work well. i have
been told that this patch is slated for update 4.
i am mainly submitting this bug so that other people can find the patch more
easily than i did.
U4 should be out now...is this problem resolved?
yes, it does fix things. sorry it took a while to be able to reboot the machine
that needed the change.
