Description of problem:
The kernel 2.4.18-5 and the one in rawhide don't seem to have support for Intel
ICH4 DMA access for disks.
Stock 2.4.19 will have support for the chipset, but also see a workaround for a
bios bug (required on intel boards):
2.4.18 doesn't support the recent Promise 20276 chip in the Ultra133 cards.
Would it be possible to include support for this in your kernel? Also there is a
bug in 2.4.19 which makes machines using a Promise Ultra100/133 hang. See:
rawhide kernel should have all of this...
