------- Additional Comments From [EMAIL PROTECTED] 2006-01-01 06:52 ------- First, forget anything I've ever said about 2.6.15-rc5-mm3 (or other -mm-s). I unfortunately tagged along on a bugreport that was, and is, totally unrelated to the present issue. Sorry - won't happen again. My local fix was just a sledgehammer, intended for this machine only. Regarding your other queries: _Unpatched linux-2.6.15-rc7_ image = /boot/kernel-2.6.15-rc7-c1 label = 2.6.15-rc7-c1 root = /dev/hda2 append = "processor.nocst" active state: C1 max_cstate: C8 bus master activity: 00000000 states: *C1: type[C1] promotion[--] demotion[--] latency[000] usage[00000000] _Patched linux-2.6.15-rc7_ http://bugzilla.kernel.org/attachment.cgi?id=6743&action=view (from bug 4485) image = /boot/kernel-2.6.15-rc7-c1 label = 2.6.15-rc7-c1 root = /dev/hda2 active state: C1 max_cstate: C8 bus master activity: 00000000 states: *C1: type[C1] promotion[--] demotion[--] latency[000] usage[00000000] >From my foggy understanding of the code, "pr->flags.power = 1" will never be >set for anything lower than C2 - in accordance with linus' intent. Which is fine... I don't mind patching locally. I'll attach an acpidump as per request, but I'm rather confident in its 'correctness'. _Slightly OT_ I've tried hacking include/acpi/processor.h (upping ACPI_PROCESSOR_MAX_C2_LATENCY to overcome the manufacturer's sneaky 101 value), and then 2.6.15-rc7 proper uses both C1 and C2. The downside is that this leads to - significantly - _less_ powersave and _higher_ temperature than plain C1. On an amd64 processor something has to be done with the PCI bridge to enable C2. Can not find the correct info on the net. Phew, time to go. ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
