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.
