Fn keys have to be pressed multiple times after suspend

Hi, I'm having some problems with my Fn keys and I can't even start to pin-point this to a specific component. Any help would be appreciated.

After some suspend-resume cycles, some of my function keys have to be pressed multiple times in order to work.

Example:
Fn + Esc is bound to mute/unmute.
after a few suspend-resume cycles, I have to press Fn + Esc and then Fn Fn Fn Fn for the sound to be finally muted/unmuted. This gets worse with the number of suspends. The count right now is 7 Fn key presses.. =)

This happens with mute(Fn+Esc), screenlock(Fn+F1), brightness up and down(Fn+F6,F7), but does _not_ happen with volume up and down(Fn+3,4) and numlock(Fn+F11). The other Fn keys are not configured.

I realize this is very similar to https://bbs.archlinux.org/viewtopic.php?id=159796, but I didn't want to enter in the whole brightness-control-in-laptops thread.

xev shows nothing on the first key presses. When the last one is performed it shows:

for Fn+Esc:

KeymapNotify event, serial 37, synthetic NO, window 0x0
    keys:  2   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   
           0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0

And for Fn+F6,F7 a burst of:

FocusOut event, serial 37, synthetic NO, window 0x2c00001,
    mode NotifyUngrab, detail NotifyPointer

FocusIn event, serial 37, synthetic NO, window 0x2c00001,
    mode NotifyUngrab, detail NotifyAncestor

KeymapNotify event, serial 37, synthetic NO, window 0x0,
    keys:  0   0   0   0   0   0   0   0   1   0   0   0   0   0   0   0   
           0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   

RRNotify event, serial 38, synthetic NO, window 0x2c00001,
    subtype XRROutputPropertyChangeNotifyEvent
    output LVDS1, property Backlight, timestamp 242331224, state NewValue
                             (and 35 more of this, with different serial ##)

I'm on a Toshiba Satellite Z930
Arch with xfce4
The Fn keys (all of them) are configured through xfce's Keyboard Settings.
