Erratas are known defects in the CPU, typically found after introduction to market. Unfortunately, not all CPU libraries are able to work around all errata. You did install a CPU library, didn't you?
For the 68030: Install a 68030.library. This will avoid the "CIIN disabled on write" errata.
For the 68060: If you cannot use the generic 68060.library mentioned above, add the following command to the Startup-sequence:
CPU DISABLELOADSTOREBUFFERBYPASS
