The kernel (2.2.14) thinks that these processers are in fact Pentium 
III's, and it tries to disable the serial number.  Since Athlon 
tbirds/durons do not have serial numbers, this operation fails, there is a 
kernel panic, and the system halts.  Booting off of the rescue disk yields 
the same results.

i think i have the same problem.  i get a gpf 
when disabling CPUID serial number in boot on
a duron 600 (tyan 2390 board).  i can boot off
cdrom and other oses are fine.  i tried installing 
the smp and boot kernels from the cdrom to no avail...

i noticed that the cpu was running a little hot
77 - 80 C -- maybe this is just the gauge...

the CPU vender id comes up AMD on the boot 
messages and linux/arch/i386/setup.c looks like
it only trys to turn off the serial # if the
vender is intel (from 2.2.14 on kernel.org):

i'll try upgrading to 2.2.16 -- though nothing has
really changed in this bit of code in 2.2.16...

I figured out how to fix this problem from LILO.  At the prompt, type "linux 
x86_serial_nr=1".  This makes sure the kernel does not try to turn off the 
serial number (bad on processors that don't have them :-))

Everything should boot fine.
