Cache?

But I have some thought on if perhaps it could be related to the microcode
version of the CPU. Mine reports microcode rev. 3. Firmware rev. 83.

I have a problem that when I have heave I/O to my CMD controller, the
whole CPU freezes. Only a power cycle will help.
But VMS works fine.

What can others report?
