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.
