Description Need Real Name 2000-10-21 16:33:46 UTC
Hello there!,
    I have been trying to install RED HAT 6.2. Installation completes and while LINUX attempts to complete a reboot-causes the process to 
hang 
with the readout below. Several users on the RED HAT DISCUSSION GROUPS have the same problem We all have an ATHLON 
PROCESSOR. Mine is a 750mhz screamer built by GATEWAY. Any suggestions????????
yours,
Steve z

 This seems to be a bug with the kernel trying to 
disable the CPU ID number which causes it to panic
on Athlons.

A way to resolve it is to type the following
at the LILO prompt:

LILO: linux x86_serial_nr=1

Another solution is: once the above solution gets
you into the system , use linuxconf to add that parameter
to lilo so that you don't have to type it in everytime.

Third solution: recompile kernel.

This information is correct as to how to workaround the problem.
