Description merlin 2016-09-18 12:06:08 UTC 
Emerging app-laptop/tp_smapi doesn't fail but warns about unknown symbols causing the tp_smapi (and hdaps and thinkpad_ec) kernel module unusable.

Here is the full emerge trace.

Does this only occur on kernel 4.7?

Also, please attach emerge --info

I don't know, first time I'm trying to emerge tp_smapi.
Comment 5 Michael Orlitzky gentoo-dev 2016-09-22 11:59:36 UTC 
That version of tp_smapi should work with 4.7 kernels. I guess the first thing I would check is that the kernel in /usr/src/linux is built, and actually corresponds to the config file at /usr/src/linux/.config. Double check that /usr/src/linux points to /usr/src/linux-4.7.2-gentoo, too.

Most of those warnings (e.g. missing strncpy) aren't specific to tp_smapi so I'm thinking there's something wrong with the kernel source/build. You can also try to emerge some other out-of-tree kernel module, like net-fs/openafs-kernel or sys-fs/zfs-kmod. If every out-of-tree module throws the same warning, that gives us some useful information.

I just upgraded to 4.7.5 and removed all older kernels. It persists.

Is it possible these symbols get stripped somehow? CONFIG_STRIP_ASM_SYMS is not set.
Comment 7 Michael Orlitzky gentoo-dev 2016-10-02 23:43:48 UTC 
Do you have CONFIG_TRIM_UNUSED_KSYMS=y? If so, can you try disabling it?
Comment 8 merlin 2016-10-05 12:58:24 UTC 
That's the right option I activated during a kernel upgrade.
I thought it was CONFIG_STRIP_ASM_SYMS.
Thank you.
