VMware passthrough problem after updating to 4.1 Update 1

I am using 2 X HP DL360 G6 in cluster mode (vSphere 4 advance).
Recently I upgrade both ESX servers from version 4.1 (4.1.0, 320092) to 4.1 Update 1 (4.1.0, 348481).
After the successful process I wasn't able to start one of the VM's that uses pass-through nic card.
I reconfigure the pass-through nic card, restarted the host but when I'm trying to add pci device, it shows that the device is unavailable.
I even try to vmotion the machine to the other host and configure it from the beginning but the same results.

I guess that it something to do with the Update 1 because everything works fine before the upgrade

It's possible that U1 has broken something, we ususually wait for "all the pegnuins to have left the iceberg" before we apply any new updates from VMware to production servers.

I've not seen a few issues with U1, but not this one.

I think this issue, you are going to have to open an SR with VMware. So it's logged with them, to investigate a fix or patch. But in the meantime, the workaround they propose will be the same from me, rollback.

does the NIC show as available for pass-through on the Configuration|Advanced Settings page after you reboot?

oh, and do you see the same results if you connect directly to the host with the vSphere client instead of going through the vCenter server?
