[Bug 446717] Re: [gm45] Adjusting Brightness in Acer Aspire Timelines causes system freeze in 4810T and 5810T models

 

When I examined the function key press using logkeys (http://code.google.com/p/logkeys/) 
I noticed that a single key press of the Function key alone registers two times.

<E-1d0><E-1d0>

The documentation for the logkeys logfile format, indicates that 1d0 is
the keycode in hexadecimal format. Perhaps this registration of this
keypress two times is contributing to the error?

Is the patch mentioned by Martin in comment #60 supposed to remove the
instability during brightness adjustments? I'm using kernel version
2.6.38-8 and still experiencing the issue.

I am not sure where to check in the /sys or /proc filesystem to
determine the number of brightness levels that are supposed to be
available to the system, or the current setting.
