No boot after upgrade to 77 (4.9.40-eve-ng-ukms+ kernel)

Hi,
I'm having some issues since upgrading EVE to r77, if I attempt to boot using the 4.9.40-eve-ng-ukms+ kernel then I get a blank screen and my server no longer boots. I can boot on the vanilla kernels no issue, and i can boot on the old kernel based on 4.4 but absolutely nothing with this new kernel. Has anyone else seen a similar issue?
Running baremetal on Ubuntu 16.04.3 LTS
Server: Dual e5-2650 / 128Gb RAM / intel 82559 10GbE NIC

Some systems have problems regarding splash screen
in /etc/default/grub
comment lines:
GRUB_CMDLINE_LINUX_DEFAULT
GRUB_GFXMODE
and type update-grub
then retry

Please note that it this works, you have to do the same after each upgrade....

Hi,
Thanks for replying, unfortunately that hasn't resolved it, i was getting the splash screen when i booted successfully into the older kernels, however now for the new kernel it just seems to hang after 'loading initial ramdisk' statement.

ok then uncomment :
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash vga=788"
but repcae it by
GRUB_CMDLINE_LINUX_DEFAULT=" noquiet "
update-grub
You will be able to see boot process and where server hangs....

You can reach us on skype
BTW,
when booting with legacy kernel, type df -h and show me the result... I suspect a partially ramdisk creation.....

Hi,
Thanks for your replies so far, I tried to noquiet the boot but i don't get anything at all once i try and boot that kernel, i get to loading initial ramdisk.... then it freezes, i get nothing after that.
Code: Select all
root@eve-ng:~# df -h

udev 63G 0 63G 0% /dev
tmpfs 13G 14M 13G 1% /run

Above is a printout of my df -h if i boot into 4.4.0-96
Code: Select all
root@eve-ng:~# uname -a

I can boot up in the old custom 4.4 kernel, however it leaves me with no NIC config (even though my NIC is found in the dmesg output / lspci), so i'm kind of stuck now, as i can't even just rollback to using the old custom kernel.
Is it entirely possible that there are some kernel modules missing from the 4.9 ramdisk that are in the 4.4 ramdisk which is stopping me from booting?
