Date: Wed, 30 Jan 2008 00:51:45 -0800 (PST) [thread overview]
Message-ID: <bug-9848-3570@http.bugzilla.kernel.org/> (raw)
http://bugzilla.kernel.org/show_bug.cgi?id=9848
Summary: acpi-cpufreq: Incomplete freq list on ASUS P5N32-E SLI
PLUS with Intel(R) Core(TM)2 Quad
Product: Power Management
Version: 2.5
KernelVersion: 2.6.24
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: cpufreq
AssignedTo: cpufreq@www.linux.org.uk
ReportedBy: patrol@sinus.cz
CC: venkatesh.pallipadi@intel.com, trenn@suse.de
Latest working kernel version: N/A
Earliest failing kernel version: 2.6.23 (earlier kernels not tested)
Distribution: Vanilla kernel (no commonly known distro)
Hardware Environment:ASUS P5N32-E SLI PLUS MoBo, Intel(R) Core(TM)2 Quad CPU
(with constant TSC), 2G RAM
Software Environment:64bit binary (x86 Linux architecture), vanilla kernel,
booted by LILO, latest BIOS (0901)
Problem Description: Only 600 and 900Mhz clocks available in cpufreq-acpi. The
real CPU clock is 2.6 GHz - it is 2.4G CPU with overclocked FSB. When the
"Intel Enhanced Speedstep" feature is disabled in the BIOS, system runs at 2.6G
and cpufreq is not available. When the feature is enabled, the system seems to
run at 900M with no possibility to accelerate, just decelerate to 600M.
Steps to reproduce: Use the above mobo/cpu, enable "Enhanced Intel Speedstep"
in BIOS, load 2.6.24 kernel with acpi-cpufreq.
