[Sunhelp] "Fast Data Access MMU Miss

[Leon Halford - Open Systems Solutions Ltd]

Try disabling the external cache on the cpu's before booting, then 
upgrade to the latest OpenBoot PROM. 
(This procedure is required for the new 400Mhz 8MB processors when 
used in Ex000 servers and no doubt the same scenario is applicable 
for some other cpu/server varieties.) 

The "MMU Miss" is also sometimes avoidable if you persevere with
network vs CDROM vs disk installations. But ideally you want to
eliminate it by using the above procedure. 
 
The PROM command to disable cache is something like "limit-ecache".
Use "sifting ecache" to get the exact command syntax.

I am trying to boot a hard drive loaded on one SPARC machine on another
SPARC machine, and am getting the following error:

"FAST DATA ACCESS MMU MISS"

Does anyone know what this means and how I can get around it so I can
boot the drive on the new machine?

Thanks.
