Hi - My first post here. I was unable to boot back up after upgrading to 6.6.6. I was didn't get a chance to plug a monitor in to see any error messages but I was able to check my network activity and see that it never got back on the network. I am using a 10gb NIC and I saw that the 10gb driver was updated or changed in the release notes. Perhaps it could be an issue? I was able to revert back to 6.6.5 and boot so I am stable at the moment. Any ideas?
