yes, when I select the 2.4.18 kernel from lilo it is booted and seen as the proper version.

nope, I even tried removing the file and recompiling the kernel with the make modules and make modules_install commands. Filesize comes up as zero still.

I checked my 2.2.16 modules.dep file and it shows about 30k for filesize.

Ok, shell scripting isn't a real strong point of mine right now but if scripts are like C++ or Java programs that run from the first line of main to the last then the file-system is read-only while rc.modules is run.

dmesg doesn't give me much, this is strange because at startup I clearly see the messages about my modules failing to load at startup, but there is nothing about my modules in dmesg or any of the log files.

/var/log/system did give me a interesting message until I recompiled the kernel.

Before kernel recompile -

Inspecting /boot/System.map
no module symbols loaded

After recompiling the kernel -

loaded 164128 symbols from /boot/System.map
Symbols match kernel version 2.4.18

I have been doing some reading about these problems online. All the solutions in archived usenet posts and people's own fixes suggested recompiling the kernel. I tried that and am still no closer to solving the missing module mystery.

According to the kernel changes doc I need egcs 2.91.66 (which I believe I have) or gcc 2.95.3.

The reason why I think I have egcs setup as my compiler is when I do a locate on gcc I get this:

/usr/lib/gcc-lib/i386-slackware-linux/egcs-2.91.66


I have read quite a few usenet posts that suggest using gcc over egcs for kernel compiles. So I downloaded gcc 2.95.3 The other day and was planning to install the compiler tomorrow and try to compile with gcc instead of egcs.
