I can't log into the host neither via SSH not the mgmt. Papaul, can you have a look the next time you're in the DC?

Logins are failing with "Connection closed by UNKNOWN port 65535"

This happens after the key is offered for authentication.

The mgmt on ms-be2016 actually works, it's one of those old servers which have a very outdated SSH version which doesn't negotiate current SSH kexes, but a login with when explicitly selecting "diffie-hellman-group14-sha1". When logging in no console is available and it's just printing "rejecting I/O to offline device" every second.

After a power cycle the host is up just fine again, there's nothing in kern/syslog by the time of the crash. Filippo is checking whether there's a firmware update available for the RAID controller.
