TLB Miss booting linux kernel on ppc 405

[Robert Woodworth]

Have you solved your problem??

I'm having the *EXACT* same problem on a Virtex4FX60.
The device is configured with PLBv46/MPMC3/LL_TEMAC.

I'm under the suspicion that the PLB is issuing an error when switching
to virtual mode and that there is either a timing/synthesis error or a
fundamental error with the way the FPGA is getting synthesized with the
PLB.
