Hi, PowerTOP 1.97 beta 1; Ubuntu 11.10 server; kernel 3.0.0-13-server x86_64.
Any "tunables" that I toggle in PowerTOP revert to "bad" on rebooting my server. The "tunables" in question are: Bad Enable SATA link power management for /dev/sda Bad VM writeback timeout Bad Enable Audio codec power management Bad Autosuspend for USB device USB Storage (Generic) Bad Autosuspend for USB device disgo [2-3] Bad Runtime PM for PCI Device Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #4 Bad Runtime PM for PCI Device Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #5 Bad Runtime PM for PCI Device Intel Corporation ICH9M/M-E SATA AHCI Controller Bad Runtime PM for PCI Device Intel Corporation Mobile 4 Series Chipset Memory Controller Hub Bad Runtime PM for PCI Device Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller Bad Runtime PM for PCI Device Broadcom Corporation NetXtreme BCM5761e Gigabit Ethernet PCIe Bad Runtime PM for PCI Device Intel Corporation 82801I (ICH9 Family) USB2 EHCI Controller #1 Bad Runtime PM for PCI Device Intel Corporation 82801I (ICH9 Family) PCI Express Port 5 Bad Runtime PM for PCI Device Intel Corporation 82801I (ICH9 Family) PCI Express Port 1 Bad Runtime PM for PCI Device Intel Corporation 82801I (ICH9 Family) USB2 EHCI Controller #2 Bad Runtime PM for PCI Device Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #6 Bad Runtime PM for PCI Device Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #1 Bad Runtime PM for PCI Device Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #2 Bad Runtime PM for PCI Device Intel Corporation 82801I (ICH9 Family) HD Audio Controller Bad Runtime PM for PCI Device Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #3 I've tried (where I can) to change the settings for the listed "tunables" manually in the OS, but even those revert to default settings on reboot. Advice on making changes implemented through PowerTOP stick would be much appreciated. S.
