[opensuse] x86_64 11.2 kernel compile and boot error continued

When you're doing your config (i.e. through make menuconfig or, more friendly, make xconfig), either disable thermal_sys or configure it to be included in the kernel rather than as a loadable module. Or...
Use --alow-unsupported or set allow_unsupported_modules to 1 in /etc/modprobe.d/unsupported-modules
Follow this instruction - it pretty clearly tells you where the problem is; thermal_sys.ko is an unsupported module and you have allow_unsupported_modules set to 0, so the kernel is configured not to allow it to load. (I'm pretty sure that this option is also settable at configure time). At that point, the kernel seems to stop loading any additional modules (including your filesystem drivers). -- =================================================== Rodney Baker VK5ZTV rodney.baker@iinet.net.au =================================================== -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Not only is thermal module not loading, all of them seem to be skipped with this same problem. I don't want to disable it or include in the kernel. I want to build the kernel as shipped. I know I can include all of these drivers in the kernel and then I can even tune so that my kernel will only use drivers and features that I want to use. However, I am trying to fish out why these drivers are not working. Something else is the problem. Right? Suse will ship kernels which match their source/config right?
Or...
Use --alow-unsupported or set allow_unsupported_modules to 1 in /etc/modprobe.d/unsupported-modules
I appreciate this answer as well, but I don't see how I can do it. I thought the modules were needed in order to read the file system. How will it be able to read this config file if the file system modules are not loaded? Please forgive my ignorance.

I looked in menuconfig under "Enable Loadable Module Support" and all options are enabled. Nothing here says skip unsupported modules. There is the part about versioning support. I'll play with this, but I thought this was a safety check to prevent kernels and modules being mismatched. Anyway, this sounds like a work around to me.

Right.

I tried to build a kernel without module version support. My problem still existed. I wonder if this is something do with this tech note? http://developer.novell.com/wiki/images/8/80/Kmpm-code11.pdf It mentions that kernel drivers need to be signed? Otherwise they are unsupported? Could this be the problem? John -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I never use mrproper, with a kernel from openSUSE at least ...

1. Fresh Install 2. cd /usr/src/linux 3. make oldconfig
I use "cloneconfig", which clones the configuration of the running kernel. There is a suse readme file in "/usr/src/linux", have a look at it.
4. make 5. make init 6. make modules 7. make modules_install 8. make install 9. reboot
