** Description changed:
+ === 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.
- 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://wiki.ubuntu.com/Kernel/KernelBootParameters.
