CentOS - Aug 2020 - CentOS 8 kernel-4.18.0-193 shim issue

Hey All,

Is it safe to allow the 193 series kernel update now?  Last time I tried 
that my system refused to boot.  I had to roll back to the 4.18.0-147 
kernel to get my machine to reboot.

Since that happened I've been watching this mail list for 
acknowledgement that the problem has been corrected while refusing the 
kernel update.  I may have missed the announcement that the issue was 
resolved and the the update is now approved.

I was successful in installing the latest updates on a Supermicro
X10SRL-F motherboard with an E5-2630L v4 CPU that uses UEFI for boot.

Well, I let the kernel up date run.  I haven't allowed the machine to 
reboot yet, but that's going to happen just after I send this.  At the 
moment I'm running 4.18.0-147.8.1.el8_1.x86_64 #1 SMP

It 'SHOULD' be good.  We announced it over the same weekend it was
broken.

That does not mean every single combination of firmware, hardware, etc
on every possible machine frm every manufacturer will work.  But, we
have had no reports of failure since the updates.

Ummmm..............

except for apple hardware.  My Mac-mini runs just file as long as this text:
   exclude=grub2* shim* mokutil
is added to the end of the file /etc/yum.conf

and executing
   yum -y update
and rebooting works just fine.  HOWEVER, if I 
remove that 'exclude' line from yum.conf, run 
'yum update', and then reboot, the system is 
unbootable.  I end up with a blank screen, no 
grub anything.  I have also been unable to 
recover from this.  Therefore, that exclude line stays.

I'm sorry about the delay in responding; I wanted 
to verify this on a 'crash-and-burn' MacMini.

I ran the update and did the reboot last night.  It was too late for me 
to report the results then.

Thank you to the CentOS Team.  Y'all are awesome.
