I have a laptop cemputer. When I try to load apm module, I have "unresolved symbol machine real restart" and "unresolved symbol default idle".
How can I fix thi?.My distro is Red Hat 8 with kernel 2.4.20.

Gidday!

My first guess would be that the
modules & kernel that RH ships don't
quite match. The instant-solution should be
to recompile your kernel so it all matches
...

I recompiled the kernel just to enable APM BIOS as module. But now I can't load module. There is any option needed in Kernel that I have not chosen?

why cant you load the module. ( What is the error )
did you make dep?

try running /sbin/depmod -a and see what it reports.

Errors are unresolved symbols described in my first post. depmod -a results, unresolved symbol in apm.o

I have Slackware 9 and when I compiled apm module and tried to modprobe it I received the same unresolved symbols...
Well, if someone can help me I will be very grateful. Actually apm is not very important feature, but I like bugging my Linux and I want everything to be OK

Welcome to LQ, valo!

Did you compile just the apm module ? Are you sure you compiled it for the kernel you're currently running?

Hi nxny This forum is really something great. You can read really interesting info and learn a lot about linux...

Now, about the topic... I recompiled the kernel several times, also I did make deps and didn't see any problems. Actually I haven't tryed to compile apm as a part of the kernel... Well, tomorrow I may try to do this... I also remember that a friend of mine have told me that he had tryed to use apm and even had tryed to compile it as a part of the kernel, but he haven't told me why he hadn't succeeded...
When I searched in google about this problem I found that other people have the similar problem and I think that may be one of the solutions is to edit some source files of the module!!!
I will continue searching solutions, but if you tell me how to fix this I would be very grateful

P.S. : sorry for my english... I need more practice)

LQ kicks some.

The APM drivers are part of the kernel. Do you mean you haven't tried to build it into your kernel ( instead of building and insmod-ing apm.o)?

Here's what I have under the source dir of my running kernel.

/usr/src/linux-2.4.20/include/linux/apm_bios.h
/usr/src/linux-2.4.20/include/config/apm.h
/usr/src/linux-2.4.20/include/config/apm
/usr/src/linux-2.4.20/drivers/macintosh/apm_emu.c
/usr/src/linux-2.4.20/arch/i386/kernel/apm.c
/usr/src/linux-2.4.20/arch/i386/kernel/apm.o

I would suggest turning symbol versioning ( CONFIG_MODVERSIONS, I think ) off and recompiling.

Yes that's what I mean

Well, I have absolutely the same files, except /usr/src/linux-2.4.20/arch/i386/kernel/apm.o, because I have done make clean...

Hmmm, I must read about this... When I return at home this afternoon I will try this. 10x

I checked my configuration and this feature is turned off, I could try turning it on

How stupid I am!!!!!!!! I fixed it!
I tryed to compile a newer kernel - 2.4.21, but when I rebooted kernel said that it's version is 2.4.20 and then I realized that make install, doesn't copy the new kernel image in /boot. Actually, now I see that this is very logical, because otherwise the previous image could be deleted. OK, I configured it and everything is working now

nxny, I hope I haven't wasted your time, I feel really stupid...

Good to know you fixed it yourself. No problem.
