[NTLUG:Discuss] Redhat 7.1 and Kernel Modules Compiling issues

[Jack Snodgrass]

if you can boot...
uname -r says what your kernel is 'named'.

the rc.sysinit stuff will look in
/lib/modules/`uname -r`
directory for modules.

the rc.sysinit stuff also does a depmod -a to update your
module dependancies list. that data gets put into the
/lib/modules/x.x.x directory too. See if that is getting
updated.

Your /usr/src/linux/.config file should have
CONFIG_MODULES=y
make sure that it does.

Just a couple of things to check. Maybe the modules are being
put into the wrong /lib/module/x.x.x. directory. maybe your
kernel isn't configured for modules.... maybe the depmod thing
is not running at boot time.

lastly... if you do a
insmod filename
for one of your modules... what happens.
