Do you have any issues booting to shell or installing standard image?

Subject: [External] [xcat-user] Problem with statelite boot - no console or ssh
Good day,
I am trying to bring up a new cluster to replace our aging system, and am
trying to duplicate our basic setup - which is to say statelite provision on
Dell PowerEdge servers. After working through the documentation and looking at
our old setup, I've gotten close (I think) to success but have now been beating
my head against a wall for a few weeks.
In short, when I boot the node, it seems to come up successfully, at least as
far as networking and syslogging goes, but I can neither ssh to the node, nor
can I get a console login. I'm afraid I'm missing something obvious, but it's
starting to drive me crazy. Data to follow:
The node is a Dell C6420, the OS is SciLinux 7.4, and I'm trying for a
statelite boot.
lsdef on the node:
Object name: node-i01

when I boot with rcons running to the node I get the usual boot data and then:

So that looks good, but then it hangs.
>From the idrac console itself, I get that data and then a lot of other boot
>data before it hangs. Useful snippets from that data:
the kernel command line is being passed properly.
console tty0 and ttyS1 are enabled
the console USB Keyboard/Mouse say they are found.
systemd says no hostname, random generator for ID
swap is started
"Started Dispatch Password Requests to Console Directory Watch"
"Starting dracut cmdline hook ..."
"random: crng init done"
the network comes up then ... and is pingable
dns_resolver registered
then hangs, and eventually systemd-journald crashes and restarts.
The log messages below indicate that the node is not getting the correct time
settings (the time stamps in the logs are an hour off), which may or may not be
related.
/var/log/messages gives me this:

nmap indicates that port 22 is closed and ssh returns connection refused.
It feels like I'm missing something obvious, but (clearly) I don't know what
... any pointers?
