Bug 61739

Summary: Errata for 5.2 - problem with large AGP Apenture sizes
Product: Base System Reporter: Mikkel Georgsen <mikkel>
Component: kernAssignee: Simon L. B. Nielsen <simon>
Status: Closed FIXED    
Severity: Affects Only Me    
Priority: Normal    
Version: 5.2-RELEASE   
Hardware: Any   
OS: Any   

Description Mikkel Georgsen 2004-01-22 17:50:15 UTC 
If AGP Aperture Size is set to a value above 256MB, the kernel panics in both normal, non-acpi and safemode - using the 5.2-RELEASE CD1. Unfortunaly I only have one motherboard (KT600 chipset based) with support for larger Aperture sizes. I've tested with bootonly-5.2-CURRENT-20040122-JPSNAP.iso and it works flawless with a AGP Aperture Size at 1024MB.

Fix: 

Set AGP Aperture Size to 256 or lower value or use newer bootcd (bootonly-5.2-CURRENT-20040122-JPSNAP.iso works fine).
How-To-Repeat: Set AGP Aperture Size above 256 and boot up 5.2-RELEASE CD1.

I talked with the submitter about this problem so I will 
look at getting it in to the 5.2 errata.

Close PR since 5.3 is out now.  Sorry about not getting this into the 
errata, but at least having the PR in the database made it possible 
for other people to find the workaround here.
