The advice given was based on similar problems experienced when working
with RedHat 6.2 in a development environment. Just trying 2 help.
We could get into how he configured the source before compiling. Did
Jeremy just compile the source or use a tool like "make menuconfig" or
"make xconfig", did he save the current kernel configuration with a menu
utility and use it to compile the new kernel? There were reasons why
these questions were not asked yet, because the most common problems with
people trying a new kernel are related to omitting a step, or performing
a step out of sequence, usually boot loader related.
