For me, even on 2.6.32.8, switching cpufreq governor from ondemand to performance seems to fix the issue fine, but I haven't had to do it many times yet. Also, I don't have this problem on Core2 Duo Q9300 machines. HyperThreading turned on/off does not make a difference for the i7 machine. I have now also found one i7 machine (supposedly identical) where I seem *NOT* to have this problem. diff -u broken_dmesg working_dmesg shows: @@ -117,6 +71,14 @@ PM: Adding info for acpi:LNXCPU:05 PM: Adding info for acpi:LNXCPU:06 PM: Adding info for acpi:LNXCPU:07 +PM: Adding info for acpi:LNXCPU:08 +PM: Adding info for acpi:LNXCPU:09 +PM: Adding info for acpi:LNXCPU:0a +PM: Adding info for acpi:LNXCPU:0b +PM: Adding info for acpi:LNXCPU:0c +PM: Adding info for acpi:LNXCPU:0d +PM: Adding info for acpi:LNXCPU:0e +PM: Adding info for acpi:LNXCPU:0f PM: Adding info for acpi:LNXSYBUS:00 PM: Adding info for acpi:PNP0C0E:00 PM: Adding info for acpi:PNP0A08:00 @@ -177,6 +139,7 @@ PM: Adding info for acpi:device:25 PM: Adding info for acpi:device:26 PM: Adding info for acpi:device:27 +PM: Adding info for acpi:PNP0103:00 PM: Adding info for acpi:pnp0c14:00 PM: Adding info for acpi:LNXTHERM:00 PM: Adding info for acpi:LNXPWRBN:00 @@ -216,7 +179,6 @@ pci 0000:00:1d.7: reg 10 32bit mmio: [0xd0321000-0xd03213ff] pci 0000:00:1d.7: PME# supported from D0 D3hot D3cold pci 0000:00:1d.7: PME# disabled -pci 0000:00:1f.0: Force enabled HPET at 0xfed00000 pci 0000:00:1f.0: quirk: region 0400-047f claimed by ICH6 ACPI/GPIO/TCO pci 0000:00:1f.0: quirk: region 0500-053f claimed by ICH6 GPIO pci 0000:00:1f.0: ICH7 LPC Generic IO decode 1 PIO at 0680 (mask 007f) @@ -320,8 +282,6 @@ libata version 3.00 loaded.
