Unable to boot Dell PowerEdge R415 with i386 X-HWE lowlatency kernel

Bug description:
This Dell PowerEdge R415 node, "gonzo", has difficulties to be
deployed with X-HWE lowlatency i386 kernel (fail rate: 15 out of 19
attempts).
I have tried this manually in the following order:
1. Deploy this system with i386 Xenial lowlatency kernel
2. Reboot with X-HWE i386 generic kernel (linux-generic-hwe-16.04)
3. Reboot with X-HWE i386 lowlatency kernel (linux-lowlatency-hwe-16.04)
Result:
* System can be booted with Xenial i386 lowlatency / X-HWE i386 generic
kerne kernel.
* System seems to be working with X-HWE i386 lowlatency kernel, but the ssh
connection will hang:
$ myssh gonzo
Warning: Permanently added 'gonzo,10.246.72.31' (ECDSA) to the list of
known hosts.
Maybe this is why the system can't enter the deployed state.
Tested on another Dell PowerEdge R310, "pepe", it can boot with the
i386 lowlatency X-HWE kernel without any issue. So this is a bit HW-
related.
