 Posted: Thu Sep 05, 2002 6:42 pm Post subject: can't load modules |
 |
|
I have this weird problem and I don't have a clue where to look.
Just installed gentoo 1.4 on an old pentium 133.
I used the basic CFLAGS: -march=i586 -O2 -pipe
Then bootstrap, compiled a kernel, but in the end, after a reboot, the kernel loads fine, but when it comes to loading modules, it just won't load them and gives unreasolved symbols for all my modules.
I can provide .config and a list of packages if neccessary, maybe I just missed something, but I'm hoping somebody has had the same experience with this and/or knows the solution.
Some additional info:
depmod -a gives unreasolved symbols
depmod -a -F /boot/System.map gives no errors
sometimes I hook up my HD to a faster computer to compile, however when this one boots it has the same problem.
used kernel: 2.4.19-r7 (gentoo-sources)

A forum search for "modules and unresolved and symbols" turned up 66 threads. Any of them similar to your situation?

I did check before I posted, none of them is similar.
Most threads are about one or a few modules failing, others seems to have forgotten to rerun lm_sensors after a new kernel compile.
But I my case every module fails. Perhaps its similar to the ones that have problems with SMP, so I tried (my single cpu computer) with and without SMP; no effect.
What about the System.map? I find it rather strange that checking the modules againt the system.map works fine, but running a depmod without it fails. Could it be some kind of problems with /proc/ksyms? |

Contrary to the depmod man page, depmod doesn't open /proc/ksyms. At least not here - it did open /proc/meminfo. Do you have module versioning turned on in your kernel? Is there a possibility of a mismatch between the /lib/modules/ directory and your running kernel? Bootloader picking up the wrong kernel? Inadvertent failure to mount /boot? Changed something big in the kernel config and didn't run make mrproper and dependencies got messed up? Didn't run make modules_install?
The fact that it works with System.map leads me to believe there must be some sort of mismatch. Sorry it's hard to pin down how it could happen.

I checked and dubble checked everything you mentioned, however everything seemed fine.
I reinstalled everthing allover again and now it works, so I must have missed something during my first install.
I'll probably never find the real reason for the modules not loading, I'm glad it works now.
