Description of problem:
On tyan 2882 dual opteron the fedora core 4 installer panics early in the boot
process. we have motherboards with bios version 2882 204 and 303 (latest) 2GB of
f ram dual 244 or dual 252 cpu's. two run fc3 currently without problems, 2
we're trying to install fc4 on. bios is set with failsafe defaults.


Version-Release number of selected component (if applicable):
Linux version 2.6.11-1.1369_FC4 (bhcompile.redhat.com) (gcc version

How reproducible:



Steps to Reproduce:
1.insert cd 
2.boot 
3.panic
  
Actual results:

expect it to boot.

Additional info:

booting with acpi=off or setting the bios to non-acpi-aware os does not change
the situation.
