The system hangs at boot up now. Rolling back to the old kernel everything works as expected. It appears to hang while trying to enumerate an SD card device, which isn't even installed. I have tried this on a Dell R620 and R820 and both have the exact same problem. I even downloaded a new installer iso from the daily builds to reinstall the OS and the installer hangs too now. Support for Dell PowerEdge 12th gen servers appears to be broken with kernel 4.15.0-15. https://imgur.com/VT9zd0w https://imgur.com/4BQPCXo To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1765232/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
