ATI Radeon IGP 320M and Kern. 2.4.21-pre2 Warnings/Problems...

Hello

In trying to help out the issue with the Radeon IGP Chipsets, I have posted out the problems that occured on my system. This is a Readon IGP 320M chip, running on a Compaq 900Z. BTW, these logs don't include loading sound driver. Sound driver cause the my hda, hdc links to timeout, and the hard drives are completely inaccesable till i remake kernel without them.
