Summary:                    Zaptel crashes kernel - zt_init_tone_state
Description: 
When zaptel is compiled and installed on my system, any use of my TDM400P
card will eventually lead to a kernel crash - see attached trace.

The problem is reproducible by simply picking up a Zap channel handset. It
won't always crash straight away, though. Sometimes it takes longer to
crash, sometimes it's quicker - and I also get some really strange
"dialtones" varying from complete silence, through loud single tones, right
up to weird multiple tones similar to a fax or modem.

I don't believe this to be a hardware issue, as this system has been rock
solid under an older version of zaptel. The older zaptel versions no longer
compile cleanly under current kernels, however, so it's time for me to bite
the bullet and try to track down the cause of the crash.

Any suggestions gratefully received - where do I start?!
