dmesg output
Has this worked on previous linux kernels? Can you test with gentoo-sources-2.6.31-r3. What is the output of cat /proc/acpi/processor/CPU#/power Are you using the latest bios for your system. What system is this? I see you're limited in your cstates from your dmesg. ACPI: CPU0 (power states: C1[C1] C2[C2]) Created attachment 208143 [details]

Yes. But Bios won't be the problem because i'm just searching for a way to tell BIOS under linux to use deep sleep states. > What system is this? HP Compaq 6820s for dmidecode output see attachment > I see you're limited in your cstates from your dmesg. > ACPI: CPU0 (power states: C1[C1] C2[C2]) Also when running on battery C3 sleep states are unlocked. So maybe somebody out there knows how i can tell Bios to unlock the rest of the C-states. In case this never worked or will never work i'm wondering why documentation says: "... overrides any DMI blacklist limit." Any further ideas? > > Are you using the latest bios for your system. > Yes. But Bios won't be the problem because i'm just searching for a way to tell > BIOS under linux to use deep sleep states. Hmmm. Here's a thread concerning with the same issue where a BIOS upgrade solved the issue. https://bugzilla.redhat.com/show_bug.cgi?id=425812 It might not be possible on your system. http://arkiv.netbsd.se/?ml=linux-acpi&a=2008-06&t=7787773 I see you tried to use processor.nocst and got an error msg: Booting kernel: `' invalid for parameter `processor.nocst' Can you change that to processor.nocst=1 but this might limit you to a single state which is not what you desire. e |
