PROBLEM: (83399) (PATCH ID: OSF505-240)
********
This patch fixes a kernel memory fault and invalid memory ifetch panic
which can occur in systems running Quadrics' RMS software.
A typical panic follows, where the faulting virtual address 
and faulting pc are both zero:

trap: invalid memory ifetch access from kernel mode

    faulting virtual address:     0x0000000000000000
    pc of faulting instruction:   0x0000000000000000
    ra contents at time of fault: 0xfffffc00005bde78
    sp contents at time of fault: 0xfffffe05449bf760

panic (cpu 3): kernel memory fault
