What's the content of /proc/cmdline?
On the node that works :

Code: Select all

# cat /proc/cmdline 
BOOT_IMAGE=/boot/vmlinuz-3.10.0-1160.15.2.el7.x86_64 root=UUID=bbadbeee-a193-4284-8f95-5ee70502b12c ro crashkernel=auto rhgb quiet intel_pstate=disable LANG=en_GB.UTF-8
On the non working node :

Code: Select all

# cat /proc/cmdline 
BOOT_IMAGE=/boot/vmlinuz-3.10.0-1160.15.2.el7.x86_64 root=UUID=bbadbeee-a193-4284-8f95-5ee70502b12c ro crashkernel=auto rhgb quiet LANG=en_GB.UTF-8
the intel_pstate isn't making it into the commdndline, despite being put in /etc/default/grub, using grub2-mkconfig, checking it's in /boot/grub2/grub2.cfg and rebooting. The kernel seems to be ignoring it at boot time.....

Cheers.

/boot/grub2/grub2.cfg
Wait, my legacy grubs are: /boot/grub2/grub.cfg

What else do you have in /boot/grub2/
and what do you have in the "good" node?

Whell wouldn't you know it, I did a

grub2-mkconfig -o /boot/grub2/grub.cfg

And rebooted and now it seems to be working, time to update my compile / build notes.

Cheers everyone.
