I've noticed an odd annoyance recently on a mandrake 6.1 system I've been messing with.
The core kernel is 2.9 with patches up to 2.13pre. I decided to skip all that and downloaded a complete 2.14 kernel source. After config, compile, and editing lilo, I noticed the message "Kernel version incorrect in system.map" when booting the new kernel. Other than that I haven't noticed any other problems with the new kernel, everything seems to be running fine.
Anybody ran into this before?
