RT3090: When I deactivate the WiFi Ubuntu crashes

[Simón Franquiz]

Hi, Im reporting the issue because I have been turned into a Headache for me. Every time I deactivate mi WiFi (by clicking on the wifi button of the keyboard, by software using rfkill or by right clicking on "Network Wireless") the ubuntu crashes by freezing, nothing responds and I just have to shut it down forcing it by holding the power button or taking off the battery. Not even Ctrl+Alt+F<whatever> works.

Also, when the machine sleeps, suspend or hibernate process is taking places, the same situation happens due to the wifi to turn off.

Lastly, when I start the machine with the wifi powerd off by harware, the ubuntu crashes on the log screen. I have to reboot it back, using a Windows partition, enable wifi again and then reboot it from the ubuntu partition.

I have a HP ProBook 4420s, my wireless is Network controller [0280]: RaLink RT3090 Wireless 802.11n 1T/1R PCIe [1814:3090].
Please let me know what information could help and I will send it to you asap.

Thanks in advance.

I also tried some differents kernels and finally had to reinstall everything again and the system is like brand new installation.

A fix for this bug is available for natty with kernel 2.6.38-10.44 in natty-proposed. If you are running natty you can enable proposed and update your kernel.

On maverick the same fix might become available through a new enough backports-modules-compat-wireless-2.6.38 package or a backports-modules-compat-wireless-2.6.39 package.

Let us know whether or not this fixes this bug for you.

Thanks

Hi Wolfgang,

This is my update:

- First I really appreciate your help.
- The issue with the wireless was solved by applying the backports-modules-compat-wireless-2.6.38 to maverick,
- The issue with the lid and hibertation / suspend was solved,
- Now the Bluetooth is still not working,
- My touchpad stoped doing two finger scrolling and this option became grayed out, so I could change it.

Thanks again if you could help me a little bit more on these issues.

Regards,
SAF
