Hi,

I get these messages, the majority of which seem to be false-positives:

modpost: Found 35 section mismatch(es).
To see additional details select "Enable full Section mismatch analysis"
in the Kernel Hacking menu (CONFIG_SECTION_MISMATCH).

and if I compile the kernel with CONFIG_SECTION_MISMATCH, it breaks resuming
from RAM.

Greetings,
Rafael
