I'm a little shocked that HP hasn't addressed this issue yet, considering it must be affecting a lot of customers who installed the latest driver.
So if you did (for some reason) want the latest driver installed, make sure the MTU is still 1500, and disable VMQ. I wonder why they changed the MTU... that seems like a really strange thing to do.
Between this and their new policy that, sometime this month, you'll need an active contract or warranty to access driver downloads, I'm not enjoying the HP support experience as much lately.
Although when I need to fix some server item under warranty, they do handle that really fast. Overnight cross shipments, and as long as I do the proper diagnostics first, they're happy to send the requested part without bothering me with questions.
So it's not all bad, but it is pretty bad when a new driver version can knock a server offline and HP doesn't even put out a notice, warning people and advising to downgrade if they run into issues?
