Dear all, Comparing power consumption with powertop for a brand new Dell laptop I found out that Debian is consuming about 6 Watts while Ubuntu is consuming 3 Watts (idle). Comparing configs I just found out that lspci -vv reports ASPM enabled 6 x for Ubuntu and 4 x for Debian. The differences are:
Ubuntu: Non-Volatile memory controller ASPM L1 Enabled Kernel driver in use: nvme PCI bridge: Intel Corp 12th Gen.... ASPM L1 Enabled Kernel driver in use: pcieport Debian: Non-Volatile memory controller ASPM Disabled Kernel driver in use: nvme PCI bridge: Intel Corp 12th Gen.... ASPM Disabled Kernel driver in use: pcieport So the exact same driver is been used and I didn't find any config within /etc/ modprobe.d or /etc/modules or /etc/modules-load.d with respect to these modules. Do you have an idea why this happens (same computer, so BIOS settings should have no impact)? Thank you very much. Best regards, Bernd
