Two questions: Has this improved with 2.2.X? What particular hardware setups cause this problem to show itself? I have a 2.1.0R system (P5/60/PCI/EISA) which has never had this behavior. > However, the rest of the system is fine even if this happens, as you > have discovered.

Sometimes it takes muliple executions of this command to have an effect, but at least I do not have to reboot to have some use of the console.
