udev and gnome-power-manager

Hi,

Recently I upgrade the udev from 141-5-i686 to 145-1-i686 in my MSI wind. Then the following problem begins:

When the system boots this characters can be seen in the screen just before udev is finished: ^@^@

I can add more characters during the whole boot process if I press Fn+F5 (the brightness hotkey).

When gnome is running, in few minutes the screen change the brightness very fast, like blinking. This problem only happens if the gnome-power-manager is enabled.

Downgrading udev fix the problem.

Does anyone know if this is something related with this particular version of udev, or can I do something to fix it?

I don't know if the following messages will help, because them can be seen with the current and with the old udev version. But they are the only ones that I think are related with hotkeys amb modules loading. So I post them just in case.

(so many times) This message is because the kernel do not map some hotkeys. Gnome do it.

Re: udev and gnome-power-manager

recently, I updated system, and now I have same problem like you had. I was not sure, what could cause this brightness fast changing. I thought about hal, dbus, udev. Never tried to downgrade udev. Now, I have udev 146. I am not sure what version I had before system upgrading.
Now, I have kernel 2.6.31, and I am not sure if udev 141 will work with this kernel...
I have MSI WIND, also...
