Problem Description:
There is no any keyboard event generated when any extended key is pressed (Fn+Fx,WWW,MAIL,etc). No any kernel log message is generated, there is no reaction in the appropriate event node file (cat /dev/input/event4)
Steps to reproduce:
1. cat /dev/input/eventX (kbd event)
2. press any Fn+Fx combination or WWW key or Euro key
3. dmesg | tail

This says that 2.6.27 works, and that 2.6.27 does not work.

Please clarify.  Is this a regression?  If so, from whcih earlier kernel version?

Thanks.
Comment 4 Yuri Astakhov 2009-02-03 12:22:36 UTC 
Oh, I'm sorry. I've tested 2.6.27 and 2.6.28, then the earliest failing version is 2.6.27.
Comment 5 Dmitry Torokhov 2009-04-14 02:41:00 UTC 
Just to confirm, 2.6.26 produces the keyboard events and 2.6.27 does not, right?
Comment 6 Dmitry Torokhov 2009-10-20 05:08:27 UTC 
Yuri, could you tell me if booting with i8042.dritek kernel option enables the Fn keys?
