Description of problem:
When running kernel 2.4.9-6 on a motherboard with SiS730 chipset, I 
repeatedly get IDE dma_intr errors like the following:

Oct 22 12:46:12 accessgroupinc kernel: hdc: dma_intr: status=0x51 { 
DriveReady SeekComplete Error }
Oct 22 12:46:12 accessgroupinc kernel: hdc: dma_intr: error=0x84 { 
DriveStatusError BadCRC }

This system has been stable and running 2.4.3-12 for a number of weeks.  I 
backed out to 2.4.3-12 and am no longer getting the error messages.

I should mention that looking at the system logs, the newer kernel version 
seems to identify the discs as UDMA100 while the older version identifies 
them simply as (U)DMA.

I should probably also mention that I have not seen any evidence of file 
corruption when running under either the old or new kernel.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Install RedHat 7.1 on a system with IDE hard drives running SiS730 
chipset.
2. Upgrade to kernel 2.4.9-6.
3. Watch the fur fly.
	

Additional info:

The RedHat Network is a neat idea, but I'm going to think twice before 
just blithely upgrading the kernel because it's so easy now.
