Kernel panic during shutdown/reboot with Tru64 5.1b-3 (PK5)

Hi Managers,

Has anyone experienced kernel panics during shutdown/reboot when using the latest Tru64 5.1b-3 (pk5) ?

It doesn't seem to be related to the actual PK5 installation operation and doesn't impact system stability, the panic seems to occurs later when the system is subsequently shut down (shutdown -h now) or during a scheduled reboot.

thanks.
