Subject: RAC no more HA after upgrading to 9.2.0.6?

Hello,
after upgrading a two nodes RAC from 9.2.0.4 to 9.2.0.6 I got a = surprise.
If a node don't see a link up on it's interconnect NIC than it doesn't = give anymore service.

For example, in my environment, when unplugging the interconnect one = node is evicted (rightly) but the other one, still up and running, = doesn't respond anymore as long as the interconnect link is down. If I = replug the cable the instance is back working again.

It means I cannot reboot one of the two nodes anymore since the other = would stop working.
In previous RAC version the behaviour was different and RAC guaranteed = high availability (sort of).

Is anyone experience the same issue?
Has anyone tried to unplug the crosscable or turn off the interconnect = switch in a 9.2.0.6?
What's the result?

Any feedback is welcome.
Fabrizio
