Re: [gentoo-user] unknown symbol request_module
Hi cuciferus, Thanks for pointing me to the gentoo wiki hardware list. It's impressive. Still it does not have the Gericom Supersonic 1000 which I am setting up. I did find a .config on the net for the 2.4.18 kernel http://techinfo.system33.de/LinuxOnGericom/index.html http://www.tutorials.de/forum/linux-tutorials/144865-linux-bericht-debian-auf-gericom-notebook.html (no .config posted) but the 2.6 kernel config file is quite different, it seems. Anyway, it would be interesting for me to find out the reason for the described problem. I have found a similar mail from someone else not for sound, but without solution/reason. How can a kernel module not not know about the request_module symbol from vmlinux?

Re: [gentoo-user] unknown symbol request_module
Hello Xavier, here is the .config. I just realized that there went something wrong when I put dmesg output onto the USB stick: the file is empty. But as mentioned there are a lot of Unknown symbol entries. All but request_module are from sound modules. Many thanks for your help.

[gentoo-user] unknown symbol request_module
Hi, I am installing Gentoo on an older notebook of mine and have the following problem: After a first try to make sound work, where I had OSS checked in the kernel configuration, I followed the gentoo alsa guide http://www.gentoo.org/doc/en/alsa-guide.xml But got a lot of unknown symbol entries at boot (viewed afterwards via dmesg). The first seems to be the reason for the others: unknown symbol request_module. request_module is defined in vmlinux (via nm vmlinux | grep request_module) but not linked in soundcore.o (nm soundcore.o | grep request_module says U(ndefined)) Since request_module is needed to load kernel modules, no kernel modules can be loaded, and therefore symbols from such modules are not there. This leads to the other unknown symbol messages. So the question is, why request_module does not get linked properly. What I already tried: I saved the .config and did make mrproper and restored .config. Then make make modules_install But that did not help. Did somebody experience anything similar? Could somebody give me a hint how to solve this problem? Thanks in advance. Cheers. Roland
