    Gldv3 network Driver crashes with a BAD TRAP error=e ( error in mac_ether)

    807567
      Hi,
      I am porting my 10 gig network driver to solaris( gldv3 base ) . Everything seems to be fine until this crash happens , this is after a one hour of TCP traffic between the network interface and a client .

      panic[cpu1]/thread=fffffe8000425c80:
      BAD TRAP: type=e (#pf Page fault) rp=fffffe8000425820 addr=4300000c occurred in
      module "mac_ether" due to an illegal access to a user address


      sched:

      Where osm_process_sts is my interrupt function . I tried to debug using
      mdb but iam clueless.
      Iam using
      uname -a
      SunOS unknown 5.10 Generic_120012-14 i86pc i386 i86pc
      Solaris 10 8/07 s10x_u4wos_12b X86

      Solaris 08/07..

      I remember running this in solaris 10 previous release ( 02/07)

      Any help will be greatly appreciated
