I use the Ubuntu netboot options with a PXE server to install. I've installed Ubuntu 12.04 and 14.04 on these systems, and everything works great. However, when I install Ubuntu 16.04 (and this is true both if I upgrade from Ubuntu 14.04 with do-release-upgrade AND when I install a fresh copy directly via the Ubuntu 16.04 netboot image via PXE), then the install works but when I reboot the IPMI console is completely blank: no cursor, no text, no typing shows anything. I can still SSH to the system (except of course the default netboot install doesn't include sshd for some bizarre reason so I had to play some tricks and rerun the install multiple times :-/). After a lot of experimentation I discovered that if I edit the /etc/default/grub file and remove the "splash" setting from GRUB_CMDLINE_LINUX_DEFAULT variable and re-run update-grub, then things worked fine and I was able to boot properly without losing access to the IPMI console. One more note: this is definitely a kernel issue because when I choose the older 14.04 kernel (3.13 or similar) from the boot menu on the system I upgraded from 14.04 to 16.04, with the "splash" setting still in the grub config and no other changes (so userspace is still all 16.04), I had no problems with the IPMI console viewer.
