Hello,
I have a "ProLiant MicroServer Gen8" running Fedora Server 25 and Amahi 9.
Yesterday I ran #yum update" and Fedora updated almost 150 packages incl. the Kernel from version vmlinuz-4.8.6-300.fc25.x86_64 to version vmlinuz-4.9.4-201.fc25.x86_64.
After rebooting the system, the console and the /var/log/messages gets flooded with ACPI PMM issues:

Looks like some issues within BIOS / Linux power management compatibility in latest kernel.
Any ideas how I can get that fixed or at least a workaround?
Cheers!
