Doc Text:
Previously, changing the network configuration of the Hypervisor while netconsole was enabled resulted in a kernel panic ("Kernel panic - not syncing: Watchdog detected hard LOCKUP"). This kernel bug has now been fixed. The Hypervisor has been updated to include a later kernel release that does not have this bug. Changing the network configuration of the Hypervisor with netconsole enabled will not result in a kernel panic.
