GENERIC boot panic

Soekris 4801 has Geode SC1100 which has broken i8254 timer, so I make a new
kernel build adding "options CPU_SOEKRIS" and "options CPU_GEODE", but at least
the GENERIC will boot in version 8.2 (which is the last version I did for this
device) and then I proceed with a custom kernel. 10.3 refuses to complete
booting, but both of these options are still availilible, so I made a custom
kernel from a different machine and that one does the same thing. Include is
both boot logs GENERIC and NET6801 that I made. I am assuming there was a
change in the timers logic to panic instead of allowing this to continue.

Below is the custom kernel and the attachment has the GENERIC kernel.
