Hey Folks,

I've got a bit of a strange one here. I downloaded and installed
ovirt-node-ng-installer-4.4.2-2020091810.el8.iso today on an old dev
laptop and to get it to install I needed to add acpi=off to the kernel
boot param to get the installing to work (known issue with my old
laptop). After installation it was still booting with acpi=off, no
biggie (seen that happen with Centos 5,6,7 before on occasion) right,
just change the line in /etc/defaults/grub and run grub2-mkconfig (ran
for both efi and legacy for good measure even knowing EFI isn't used)
and reboot...done this hundreds of times without any problems.

But this time after rebooting if I hit 'e' to look at the kernel
params on boot, acpi=off is still there. Basically any changes to
/etc/default/grub are being ignored or over-ridden but I'll be damned
if I can't find where.

# grubby --args=acpi=off --update-kernel=ALL

I know I'm missing something simple here, I do this all the time but
to be honest this is the first Centos 8 based install I've had time to
play with. Any suggestions would be greatly appreciated.

The drive layout is a bit weird but had no issues running fedora or
centos in the past. boot drive is a mSATA (/dev/sdb) and there is a
SSD data drive at /dev/sda...having sda installed or removed makes no
difference and /boot is mounted where it should /dev/sdb1....very
strange

Cheers,
Mike
