I guess from looking at it, I should get a Kernel Error Message with "notifying SMM bios failed" message. I will check the logs (It is on a seperate HDD for this same machine (need to keep my production machine up and clean). I have installed 2.6.17 and compiled with the cpufreq debug, and here is the portion of dmesg I am sure you are intrested in: Netfilter messages via NETLINK v0.30. ip_conntrack version 2.4 (8190 buckets, 65520 max) - 224 bytes per conntrack ACPI: AC Adapter [ADP1] (on-line) ACPI: Battery Slot [BAT1] (battery present) ACPI: Battery Slot [BAT2] (battery absent) ACPI: Power Button (FF) [PWRF] ACPI: Power Button (CM) [PWRB] ACPI: Lid Switch [LID] toshiba_acpi: Toshiba Laptop ACPI Extras version 0.18 toshiba_acpi: HCI method: \_SB_.VALD.GHCI BIOS EDD facility v0.16 2004-Jun-25, 1 devices found audit(1150830156.185:2): audit_backlog_limit=256 old=64 by auid=4294967295 audit(1150830156.769:3): audit_pid=2432 old=0 by auid=4294967295 IA-32 Microcode Update Driver: v1.14 cpufreq-core: trying to register driver centrino cpufreq-core: adding CPU 0 speedstep-centrino: P1 has larger frequency (65535) than P0 (600), skipping speedstep-centrino: P2 has larger frequency (65535) than P0 (600), skipping speedstep-centrino: P3 has larger frequency (65535) than P0 (600), skipping speedstep-centrino: P4 has larger frequency (65535) than P0 (600), skipping speedstep-centrino: P5 has larger frequency (65535) than P0 (600), skipping speedstep-centrino: P6 has larger frequency (65535) than P0 (600), skipping speedstep-centrino: P7 has larger frequency (65535) than P0 (600), skipping speedstep-centrino: P8 has larger frequency (65535) than P0 (600), skipping speedstep-centrino: P9 has larger frequency (65535) than P0 (600), skipping speedstep-centrino: P10 has larger frequency (65535) than P0 (600), skipping speedstep-centrino: P11 has larger frequency (65535) than P0 (600), skipping speedstep-centrino: P12 has larger frequency (65535) than P0 (600), skipping speedstep-centrino: P13 has larger frequency (65535) than P0 (600), skipping speedstep-centrino: P14 has larger frequency (65535) than P0 (600), skipping speedstep-centrino: P15 has larger frequency (65535) than P0 (600), skipping speedstep-centrino: adding state 0 with frequency 600000 and control value 0610 speedstep-centrino: adding state 1 with frequency 0 and control value ffff speedstep-centrino: adding state 2 with frequency 0 and control value ffff speedstep-centrino: adding state 3 with frequency 0 and control value ffff speedstep-centrino: adding state 4 with frequency 0 and control value ffff speedstep-centrino: adding state 5 with frequency 0 and control value ffff speedstep-centrino: adding state 6 with frequency 0 and control value ffff speedstep-centrino: adding state 7 with frequency 0 and control value ffff speedstep-centrino: adding state 8 with frequency 0 and control value ffff speedstep-centrino: adding state 9 with frequency 0 and control value ffff speedstep-centrino: adding state 10 with frequency 0 and control value ffff speedstep-centrino: adding state 11 with frequency 0 and control value ffff speedstep-centrino: adding state 12 with frequency 0 and control value ffff speedstep-centrino: adding state 13 with frequency 0 and control value ffff speedstep-centrino: adding state 14 with frequency 0 and control value ffff speedstep-centrino: adding state 15 with frequency 0 and control value ffff speedstep-centrino: skipping state 1 speedstep-centrino: skipping state 2 speedstep-centrino: skipping state 3 speedstep-centrino: skipping state 4 speedstep-centrino: skipping state 5 speedstep-centrino: skipping state 6 speedstep-centrino: skipping state 7 speedstep-centrino: skipping state 8 speedstep-centrino: skipping state 9 speedstep-centrino: skipping state 10 speedstep-centrino: skipping state 11 speedstep-centrino: skipping state 12 speedstep-centrino: skipping state 13 speedstep-centrino: skipping state 14 speedstep-centrino: skipping state 15 speedstep-centrino: trying to enable Enhanced SpeedStep (111088) speedstep-centrino: couldn't enable Enhanced SpeedStep cpufreq-core: initialization failed cpufreq-core: no CPU initialized for driver centrino cpufreq-core: unregistering CPU 0 acpi-cpufreq: acpi_cpufreq_init cpufreq-core: trying to register driver acpi-cpufreq cpufreq-core: adding CPU 0 acpi-cpufreq: acpi_cpufreq_cpu_init cpufreq-core: initialization failed cpufreq-core: no CPU initialized for driver acpi-cpufreq cpufreq-core: unregistering CPU 0 speedstep-lib: x86: 6, model: 9 speedstep-ich: Intel(R) SpeedStep(TM) capable processor not found e1000: eth0: e1000_watchdog_task: NIC Link is Up 100 Mbps Full Duplex NET: Registered protocol family 17 Bruno / J, What should I be looking for with the patched speedstep-centrino.c? Where would this message be? In my /var/log/messages or under another log file? Thanks for all your help? Ben
