PROBLEM: (GB_G02113, 89911, GB_G01664, 89130) (PATCH ID: OSF520-181)
********
This patch fixes an ATM signaling problem.  If a
temporary network error occurs during the processing
of the T308 timer, a KMF could result from a NULL
pointer to upper connection modules. 
A typical stack would look like the following:

>  0 boot
   1 panic 
   2 trap
   3 _XentMM
   4 amComT308
   5 cmPrcTmr
   6 amActvTmr
   7 schedule_sig_timers
