ALOM wont work when KVM connected to Sun Fire V440 server

Hi,

I was asked to connect a KVM screen to a Sun Fire V440 last night so I connected it up but no joy and nothing on the KVM screen. I was told that a reboot may fix the problem so connected to the ALOM and rebooted. On the plus side, the KVM screen now works but I lost the ALOM connection.

On the ALOM output (console -f) I can watch the server start to boot and then ithangs halfway through. The last ALOM messages I see before it freezes include one about probing IDE devices and then I get an error about USB device.

I saw another post on here for someone which had the same problem but it doesn't say how it was fixed.
console -f not working in ALOM

Is there a way of getting the ALOM and KVM screen up and running together? At the moment it's either one or the other.

Thanks in advance
Jimmy

NAME
cvcd - virtual console daemon SYNOPSIS
/platform/platform_name/cvcd DESCRIPTION
The virtual console daemon, cvcd, is a server process that supports the network console provided on some platforms. The cvcd daemon accepts network console connections from a remote host (only one host at any given time). Console input is read from this connection and forwarded to cvc(7D) by way of cvcredir(7D). Similarly, console output is read from cvcredir(7D) and forwarded across the network console connection. If cvcd dies, console traffic is automatically rerouted through an internal hardware interface. The cvcd daemon normally starts at system boot time. Each domain supports only one cvcd process at a time. Caution: On Sun Enterprise 10000 domains, cvcd uses a configuration file (/etc/ssphostname) to determine the name of the host from which network console connections are allowed. If the remote console host is renamed, you must edit the configuration file to reflect that change. OPERANDS
The following operands are supported: platform_name The official Sun platform name used in packaging and code. For example, for Sun Fire 15K servers, the platform_name would be SUNW,Sun-Fire-15000. ATTRIBUTES
