Description of problem:
I use my RedHat Linux system on an Asus A7A266 motherboard (with an Ali chipset
with DDR ram, probably the cause of the problem). When I do some disk IO on my
IDE drives, the system is becoming unusable from a user point of view. 

Under heavy IDE load, il was able to get this :
rtc: lost some interrupts at 1024Hz

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

How reproducible:

Steps to Reproduce:
The hardest part will probably be to find similar hardware.
A good way is to insert a CD in the CD-ROM drive with one big file. and copy it
to the hard drive. Then just try to move the mouse and you'll notice the problem.

Additional info:

I have tried to put my hard disk in another system (Asus A7V266), pretty similar
to mine (but different chipset) and the system runs just smoothly. I already
tried a BIOS upgrade and a Kernel upgrade. I'm running RedHat's latest Kernel
RPM 2.4.9-21.
