We ran on BG/Q from before petsc-3.3 was released until now and have not
seen this error message.  You'll have to find a way to reproduce before
we can do anything else, but I'm skeptical of it being a PETSc problem.

This is the relevant bit of code (from V1R2M0):

        // Determine the physical address of the source buffer.
        uint32_t rc;
        rc = Kernel_CreateMemoryRegion (&memregion, base, bytes_in);
        PAMI_assert ( rc == 0 );


You can use a debugger to determine what arguments were used.  Either
the arguments are invalid (application corruption) or there is some
deeper corruption (or a kernel bug).
