Seeing this on my PC too. The message comes from:
/arch/x86/kernel/cpu/cpufreq/powernow-k8.c As this bug is about the boot message and not the cause of the message (probably a BIOS bug or a CPU related setting), I'll add the 'ubuntu- boot-experience' tag. ** Tags added: ubuntu-boot-experience ** Changed in: linux (Ubuntu) Status: New => Confirmed -- [Firmware Bug]: powernow-k8: No PSB or ACPI _PSS objects https://bugs.launchpad.net/bugs/440877 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
