One last feedback from me: At least on my motherboard (Asrock A770Crossfire) the reason for the missing _PSS tables is solved:
The BIOS disables C'n'Q *silently* (even when the setting is set to "Enabled") if memory modules from a certain vendor are used. In my case it were those: A-Data AD2800001GOU2 2x1024MB Kit A-DATA DDR2 800MHz CL5 If i use DIMMs from another manufacturer C'n'Q works. However, i still think that's a BIOS bug, since all DIMMs i use are JEDEC-compliant, CL5, 1,8V so no "fancy" overclocking/overvoltage modules. And for the decision to silently ignore a user setting without printing a message at POST the BIOS programmer needs a visit with a cluebat. -- Error on Boot: [Firmware Bug]:Powernow-k8: Your BIOS does not provide ACPI_PSS objects in a way that Linux understands. https://bugs.launchpad.net/bugs/331691 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
