Bug Description
=== RELEASE NOTES ===
Fujitsu Siemens Amilo M 7400 and Maxdata 7000DX wireless RF kill handling triggers a kernel panic preventing wireless from operating correctly. This may be worked around by editing your kernel command line and adding "noexec=off". (Bug:979253)
===
Original bug report:
I used to be able to turn on my Intel wireless adaptor by typing sudo modprobe fsam7400 radio=1 into a terminal, but since upgrading my operating system to Ubuntu 12.04 this no longer works.
If you could send me a new code, preferably one that could turn wireless on permanantly, I would be very grateful.
Release Notes:
The fsam7400 driver directly invokes BIOS code to turn on/off the RF switch in this platform. However, the memory pages where this BIOS code is mapped is marked as non-executable and this is what causes the issue.
WORK AROUND:
As a temporary workaround, it is possible to boot the kernel with 'noexec=off' parameters. Details on how to modify kernel parameters can be obtained in section "Temporarily Add a Kernel Boot Parameter for Testing" in https:/

A workaround you can try for the moment 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/ KernelBootParam eters).
Please let me know if this workaround works for you.
