Public bug reported:
Switching off the wireless adapter from the hard switch causes a system freeze.
Couldn't recover it since keyboard and mouse weren't responding.
My steps to reproduce this:
# Turned on machine, login.
# Connected wireless, bluetooth on.
# Noticed wireless LED indicator was off (Bug #753857), but desktop indicator
was on and connected successfully to my home network. Internet working (it is
now, as I'm reporting from Natty).
# Switched off wireless adapter from the hard-switch provided in my laptop.
Bluetooth LED turned off immediately, so did desktop indicator. Wireless
desktop indicator was still on.
# After a second, system was frozen. Got to turn off from Power button.
Tried the same steps after installing proprietary driver and the same
issue was present (Bug #753857 too).
I consider this a regression, since it works fine on Maverick with
kernel 2.6.35-28 with Broadcom proprietary driver installed.
