CentOS - May 2018 - Latest CentOS does not boot, Proliant ML330 G6

Hello all.

I just upgraded to the latest and tried to reboot: kernel panic and dead as a
brick.

Luckily GRUB still works and booting the to the next option in boot menu
succeeds.

How can this be? This OS is assumed to be solid as a brick :)

So to diagnose this problem there needs to be a lot more information supplied:
CPU type
Memory
Additional cards?
Where does it kernel panic? [Starting up network? Starting up disk
drives? Video?]

That can help determine what went borked.

It's hard to diagnose if the only thing you say is that it panicked.

If it's panicking because it can't find the root disk, then that's a
completely different issue than it panicking when it loads a
particular driver.

Do you have any excludes in /etc/yum.conf? We had an issue about a year
ago, where, in spite of exclude kernel, someone other than me ran an
update, or there was some auto-update, I don't remember, and it appeared
to *partly* install the kernel... and did not appear to do any
post-install actions (like building the ramdisk). I reinstalled the
kernel, with my usual disableexcludes=all, and the upgrade succeeded, and
all was good.

I'd loan you my magic mind reading cap but it's at the cleaners.

Appears there are unfinished transactions pending? I?m now running
yum-complete-transaction and then trying to boot.

Hard to say what it panicked for, as anything in /var/log/ tells afterwards? All
boot.log -versions before this day are 0 bytes.
