 Posted: Fri Dec 09, 2005 2:21 am Post subject: unlnown symbols in kernel modules |
 |
|
Hi,
I have been reconfiguring my kernel from scratch to try to
solve my long running virtual terminal problems.
I am on an iMac G4 and the kernel is 2.6.14-r2 I get the
following message after "make modules install": | Code: | WARNING: /lib/modules/2.6.14-gentoo-r2/kernel/drivers/video/vga16fb.ko needs unknown symbol vgacon_remap_base
WARNING: /lib/modules/2.6.14-gentoo-r2/kernel/arch/ppc/platforms/pmac_nvram.ko needs unknown symbol __alloc_bootmem_limit |
and here are the corresponding messages I get before in the process: | Code: | MODPOST
*** Warning: "vgacon_remap_base" [drivers/video/vga16fb.ko] undefined!
*** Warning: "__alloc_bootmem_limit" [arch/ppc/platforms/pmac_nvram.ko] undefined!
|
It's probably just checking an option somewhere but I won't try to boot
that kernel before knowing if it is serious (nvram scares me  ).
Any ideas what is wrong here?

I would change to the kernel source and:
| Code: | # make clean
# make pmac_defconfig
# make -j2 && make modules modules_install |
pmac_defconfig turns on just about all PowerMAC DEFault CONFIGurations. After you install the kernel and boot it successfully, run dmesg to see what hits and what misses and adjust your .config accordingly. If it dies a horrible death, try and note what is failing and disabling that in the kernel and trying again. |

Just to make sure Katphish. Does this also work work for iMacs? In short is it more a ppc config
than a PowerMac?
I won't be able to give that a try before Monday anyway.
Cheers,

Hi sorry about the delay

It is a powermac thing.
All the default config are located at /usr/src/<Your Kernel Level>/arch/ppc/configs for ppc based processors. You can more the file to see what is turned on and off if you want. |
