Bug Description

Hi,
I installed a plain Ubuntu 11.04 on my AMD based Lenovo x121e (Model 3051-5QG) with UEFI only as BIOS setting, all packages are updated to latest level (kernel 2.6.38-11), newest BIOS is installed.

I also installed the ppa for the original Realtek drivers lexical/hwe-wireless, however no change compared to plain Ubuntu driver.

Whenever I suspend the laptop and resume back, wireless is not working anymore and the FN keys (for volume, brightness, ...) are not working anymore.

A rfkill list identifies the WLAN card as hard blocked and it cannot be unblocked again. Recycling the modules or unloading them before suspending does not help.

Any clues?

Hi,
I reinstalled Ubuntu 11.04 on the x121e changing the BIOS setting from "UEFI only" to "Legacy only".

Bad news: I cannot produce the requested log file.

Good news: Everythings works fine now, Fn kes and wireless work properly after suspend/resume.

I think the root cause is more BIOS implementation bound than Ubunu, you can close the bug.

Thanks, Christian

I have exactly the same problem in 11.04 and 11.10. Unfortunately I am unable to legacy boot from a GPT partitioned disk so that isn't a solution.

Do I have to file a new report to be able to run apport-collect and confirm this?
