>Release: 5.2.1, with an update to the em driver
>Organization:
MidStream Technologies
>Environment:
>Description:
'what kernel' doesn't print the version[] string, does print a revision header from if_em_hw.h if that file is rev 1.13 or later
>How-To-Repeat:
execute 'what /boot/kernel/kernel'
>Fix:
1) Change sccspad[] initializer in sys/conf/newvers.h from { '\0' } to something non-zero. sccspad[] is supposed to pad so that sccs[] is right before version[]. What is happening is that the compiler is recognizing that sccspad[] is all zeroes and is putting it with the other variables that are initialized to zero (.bss) instead of with sccs[] and version[] (.data). See 'objdump -t vers.o'.
2) Remove the 'what' key string ("@(#)") in if_em_hw.h
