What kernel did you use? Something you built yourself? Or from your 
distribution? If from your distribution: which distribution? 

In any case, what is the full version? 

  uname -r

What zaptel version exactly did you use? From where?

You can get more useful backtraces at the kernel logs. On Debian / Ubuntu 
this will be /var/log/kern.log . On most other systems this will be
/var/log/messages . You'll probably see there a backtrace of the functions
that led to the detected lockup.
