Description Alex Xu (Hello71) 2016-08-21 23:38:13 UTC

basically no non-trivial modules will work with this on, and users are dumb and don't read Kconfig descriptions.

Please do not mark bugs about packages exhibiting the issue as duplicates, as people will not be able to search for the solution or workaround to their specific issue that way. Leave them open and make them block this bug.

+1 on adding this check. I have just tried to install nvidia-drivers on a system on which I had previously enabled TRIM_UNUSED_KSYMS in the kernel and it failed spectacularly, with both build-time errors (which I managed to work around) and nvidia.ko not loading due to undefined symbols. Fortunately I remembered there being such an option in the kernel config so I was able to fix it.

So write the patch and send it to the -dev@ mailing list.
