Problem: Black screen when I reboot after driver install

[Tanisjones]

I have a problem trying to use the latest ATI Catalist driver in Red Hat Linux Enterprise 5.1. I've installed the driver and configured the Xorg, but when I restart the system, it stops in a black screen and the system gets locked. I have followed step by step all the instructions and the ati web page, and I have also checked if the driver is ok (when i try the module using "modprobe fglrx" I don't find any problem), so I don't have any idea where the problem can be...

PS:I've tried with different versions of the catalist driver (from 8.3 to 8.6) and I have the same problem with all of them

I?ve beeninvestigating a little bit more and seems that the problem could be related with having 4Gb of RAM. I've been trying to disable the mmtr but the system still does block when it tries to load the Xwindows

[Chris Clearwater]

I have the same problem when I have at least 4GB of RAM in my system. It is a BIOS issue or a Linux kernel issue, fglrx is only one of many things affected. I also had corruption reading CDs or my USB flash drive. Try taking out a stick of RAM to see if that fixes the problem. If that is the case, you can work on fixing the MTRR issues.

This is a handy post if you are not sure how to mess with the mtrr.
