Latest kernel update has some issue with screen brightness control

Hi,

I've updated with the latest kernel, since then the screen brightness is not changing when I use Fn key+F5 or F4.

Has any one seen this issue?

Here is what I am using now.

Linux sputnik 3.2.0-33-generic #52-Ubuntu SMP Thu Oct 18 16:29:15 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

Thank you,

Insop

What bios version are you using? I have the latest kernel (12.04) and the A07 Bios and I don't have any problem.

My bios (that can be checked by "dmidecode") is "A04", that is older then A07.

Hi

After another update after the issue was found, the problem was fixed.

Yes, I am keeping up with the latest kernel (Linux sputnik 3.2.0-33-generic)
