If ACPI is enabled either in bios or in kernel, the kernel will hang
at boot.

Disabling ACPI in bios or appending 'acpi=off' to the commandline
allows booting.

Version-Release number of selected component (if applicable):
kernel-2.6.3-2.1.253.2.1

How reproducible:
Always

Steps to Reproduce:
1. Install FC2T2 on S2850
2. Reboot system after install finished
3. Yell at non booting kernel
    

Actual Results:  It hangs at boot :|

Expected Results:  It should have booted :|

What is the last thing printed before the boot hang? 
If it prints nothing, please attach the output of acpidmp 
available in /usr/sbin/ in in pmtools here: 
http://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/utils/ 
 
Any change if you boot with "pci=noapic" or "noapic"? 
 
Does any other Linux version with ACPI enabled work? 
(eg. FC2-test1, FC1 with "acpi=on", or 2.6.5) 
 
Also, please verify that you have the lastest BIOS. 
 
thanks, 
-Len
