Comment 19 for bug 1072163

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).
