this leads to a completely locked system the onoy sucsessful way out is a hard reset

the system is 
 Linux 7-of-9 3.10.10-1-ARCH #1 SMP PREEMPT Fri Aug 30 11:30:06 CEST 2013 x86_64
GNU/Linux

AMD Phenome quad core  4Gb ram  GT216 video card 1Gb  
latest Arch linux fully updated KDE 4.11.1   

This has been happening for the last 6 kernel upgrades  

Thanks for any insight 


Pete .
