[SUMMARY] BAD TRAP: type=31 in module "ifb"

Problem: System crashes periodically, seems to be when using
   OpenGL application. Messages like the following in /var/adm/messages:
   
   BAD TRAP: type=31 rp=2a10082a960 addr=20 mmu_fsr=0 occurred in 
   module "ifb" due to a NULL pointer dereference
   
Solution: Apply latest Expert3D ifb patch:
   Solaris 8: 108576-31
   Solaris 9: 112540-05

Thanks to:
