(probably there is a boot option to disable cpufreq, but I don't notice it at the moment). Yes, still try this for if it works, that would be a big clue. However, "idle=poll" is the biggest clue so far. It suggests the problem is in the ACPI or CPU_IDLE C-state code. Please try booting with "processor.max_cstate=1" If that works, try booting with "processor.max_cstate=2" If that works, try booting with "processor.max_cstate=3" and if they work, show the output from grep . /proc/acpi/processor/*/power grep . /sys/devices/system/cpu/cpu*/cpuidle/*/* The FACP(s) for this box shows that it should be trying to use _CST, but curiously, there is no _CST in the DSDT (nor any Load instructions which could pull it in) The FACP also suggests that we should not be attempting C2 or C3 (101, 1001 decimal latency, respectively) [05Fh 095 1] _CST Support : E3 [060h 096 2] C2 Latency : 0065 [062h 098 2] C3 Latency : 03E9 Please try booting with "processor.nocst" please paste the output from cat /proc/cpuinfo (I want to see if it has "monitor" in the flags") Also, if you can test with Linux 2.6.27 or later, please try "idle=halt" and then "idle=nomwait" -- Configure bugmail: https://bugzilla.redhat.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ acpi-bugzilla mailing list acpi-bugzilla@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
