Michal, the fsam7400 will have the exact same problem with recent
kernels.  This module is unmaintained and has been replaced either by
the amilo-rfkill or by the wistron_btns modules.

The issue with the wistron_btns is known, as it uses an ugly hack to
invoke BIOS code directly.  Since the memory area where the BIOS code is
mapped into is marked as non-executable (for security reasons), the
module will crash the system.

There's a workaround you can use which is to add 'noexec=off' (without
the quotes) to your kernel. You can test it by editing your boot
parameters directly on grub while booting (see the "Temporarily Add a
Kernel Boot Parameter for Testing" section in
https://wiki.ubuntu.com/Kernel/KernelBootParameters).
