Ah I remember that ncr verbose (iirc 3) boot info collected:
32bit kernel:

...hung here

mmm strange in 32bit zalon_probe() used IRQ 67 while the 64bit used IRQ 66, is that important?

Thanks,

No.  Interrupt numbers are now virtual and have no connection to how
interrupts are routed.  I'd expect them to be different between 32 and
64 bit kernels.
