Can't find sys_call_table[]

[Richard B. Pyne]

When trying to do a shutdown or reboot, I get the message 

(expletive deleted):Can't find sys_call_table[]

The only place I have ever seen this message is on one of my 
Lunar boxes. The machine is a P75-200.
Rebuild was done with:

-O3 
Pentium
-fomit-frame-pointers
-foptimize-sibling-calls
-fforece-addr
-ffalign-functions
-s

Any insights or suggestions are most welcome and appreciated.
