Subject: As2100 CPU Upgrade - halt code 6 - C-bus error
Just upgrading an AS2100 from an EV4 to EV5 CPU.
Everything works fine - as long as we run the generic kernel.
If we doconfig a new kernel and boot it up, we get a boot loop:
as it loads up the Unix symbol table...
halted cpu0
double error halt
...
CPU detected C-bus error.
Anybody handy with ideas?
