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.

According to RHEL information [1] you should be using "grubby" to update grub parameters, in your case: # *grubby --args=acpi=off --update-kernel=ALL* more acpi=off info in [2] [1] https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/htm... [2] https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/htm...

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
