Hi!

>From the docs:

Privileged register trap (11)
An attempt is being made to write to a privileged space register
or access a privileged control register without being at the most
privileged level (priv=0).
May be caused by MOVE TO SPACE REGISTER, MOVE TO CONTROL REGISTER,
or MOVE FROM CONTROL REGISTER instructions.

Do I understand correctly, that you started seeng trap 11 only
after applying your patch?

Best regards,
