6 Stable freezes upon bootup, but Release 6.0 works

[Francisco Reyes]

Have a machine that once we upgraded to 6 Stable the machine would freeze at 
the bootup menu.

We tried disabling ACPI and AIPC and it did not help. Usually the freezing occurs 
after 2 or 3 seconds out of the 10 second countdown.

To make it more interesting... if we press enter right after the menu comes 
up the machine boots perfectly fine and the machine works without
any problems.

Motherboard Tyan S515G3NR, 3WARE 2 port controller, 2GB RAM.

Tried stable from 12-6-05 (initial stable cvsup we did).. and after we 
discovered the problem we also tried stable as of 12-12-05.

Strangely enough we have a second machine with the same motherboard, same 
amount of memory, same 3Ware controller, but with different drives. the 
machine that is Freezing has 10K RPM SATA raptors and the other has some 
7200RPM western digitals (same brand as the raptors). That second machine 
works fine with 12-6 stable.

We looked at the bios levels and as far as we can tell they have the same 
bios level.

On the trouble machine I did do a custom kernel, but I don't believe the 
kernel is even loading yet at the point it freezes. :-(

Is there a verbose mode or log for the boot menu and/or the boot process?  

Given some recent bug fixes on 6 stable that correct a problem with Raid 
controllers I really would like to get both machines to 6 Stable.
