I'm seeing this on a new install and a server I just updated (to 862.2.3, UEFI both). Going back to the previous worked to get the server back online but the new machine obviously doesn't have an old kernel to go back to. Sorry for the lack of detail, just wanted to get this noted. I have not seen this random but rather consistent so far.

@centosuwuser On my side it's pretty random and only on 1 server for now. Can you reproduce this on 3.10.0-862 as well?

These servers take a while to come up and I can't get the new one online with 862.2.3. But so far, using 862.2.3 I have not had anything successfully complete the booting process and 3.10.0-862, just failed too now that I tried: kernel panic hard lockup, preceded by "BUG: soft lockup - CPU#7 stuck for 22s"

This seems to relate to this bug: https://access.redhat.com/solutions/3441101
kernel-3.10.0-862.el7 from Centos 7.5 has a bug from upstream https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=d90a10e2444ba5a351fa695917258ff4c5709fa5
You have to downgrade to a Centos 7.4 kernel or wait for next Redhat/CentOS kernel update.

I can confirm that dropping down to kernel 3.10.0-693.21.1.el7.x86_64 allows my machines to successfully boot even after fully upgraded to 7.5.1804 otherwise. I dropped the kernel back using:

awk -F\' '$1=="menuentry " {print i++ " : " $2}' /etc/grub2-efi.cfg

To get a listing of installed kernels, and then choosing the old kernel with:

grub2-set-default 2

where that number relates to the listing I get from the awk statement.

I have built a kernel-plus package with the patch referenced by @gfrankliu. Anyone wishing to test it can download it from:

The distro kernel-3.10.0-862.9.1.el7 now has the patch referenced by @gfrankliu. Therefore it has been removed from the plus kernel.
