Hi Folks, I performed a "zypper up" today, there's a new kernel bug.  After zypper's successful completion I did a "shutdown -r now".  After the reboot I logged in as myself to kde and as the various programs started to load the machine froze.  This was a complete freeze where even the numlock keyboard key wouldn't toggle. I could log in as a different user though. Looking through /var/log/messages I found a block of hundreds of ^@ characters at the crash time. So I started to search around and found an old ~/.kde4 directory.  I moved it to .kde4.save and that fixed the problem!  No more freezes. This smells a bit like something funny in an old config file that caused a buffer overrun or something.  Possibly a security threat?  Think it's worth reporting? Regards, Lew
