It was indeed set to ondemand. I changed this to conservative and the twitchyness subsided: # echo conservative > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor Using those keywords I searched and found: http://www.thinkwiki.org/wiki/How_to_make_use_of_Dynamic_Frequency_Scaling Which suggests using the sysfsutils package & editing /etc/sysfs.conf so that these settings are applied automatically on boot...I did that. * Arnt Karlsen <a...@c2i.net> [110504 10:26]: > ..try "apt-get update; apt-cache search linux-image " for better > and up-to-date ideas I'll look into trying out some of the other kernels as well. When I have more free time I'd like to tweak & compile a custom kernel for this machine. * Jörg-Volker Peetz <jvpe...@web.de> [110504 18:37]: > What kind of processor is built into your Thinkpad? % cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 13 model name : Intel(R) Pentium(R) M processor 1.50GHz stepping : 8 cpu MHz : 600.000 cache size : 2048 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov clflush dts acpi mmx fxsr sse sse2 ss tm pbe up bts est tm2 bogomips : 1196.05 clflush size : 64 power management: > What is the output of lsmod? > Maybe the kernel module used for frequency scaling is not optimal. % lsmod Module Size Used by ipw2200 130752 0 michael_mic 2256 8 arc4 1656 4 lib80211_crypt_tkip 8376 2 aes_i586 8024 1 aes_generic 27012 1 aes_i586 lib80211_crypt_ccmp 5000 1 af_packet 18932 4 usb_storage 32536 0 usb_libusual 19680 1 usb_storage usbhid 33988 0 i915 199800 2 drm 137224 2 i915 i2c_algo_bit 5124 1 i915 acpi_cpufreq 8136 0 cpufreq_ondemand 6624 0 cpufreq_userspace 2816 0 cpufreq_conservative 6920 1 cpufreq_stats 4624 0 cpufreq_powersave 1328 0 freq_table 3424 3 acpi_cpufreq,cpufreq_ondemand,cpufreq_stats sbs 11912 0 sbshc 5048 1 sbs pci_slot 4612 0 container 3468 0 twofish 6848 1 twofish_common 12856 1 twofish ecb 2676 5 ecryptfs 87628 0 fuse 56816 1 ipv6 253624 16 pcmcia 34108 0 snd_intel8x0m 13164 0 snd_seq_dummy 2572 0 thinkpad_acpi 60212 0 hwmon 2464 1 thinkpad_acpi ac 4252 0 libipw 24572 1 ipw2200 yenta_socket 22708 1 rsrc_nonstatic 10688 1 yenta_socket rfkill 17468 1 thinkpad_acpi lib80211 5428 4 ipw2200,lib80211_crypt_tkip,lib80211_crypt_ccmp,libipw pcmcia_core 31480 3 pcmcia,yenta_socket,rsrc_nonstatic nvram 6340 1 thinkpad_acpi video 20252 1 i915 output 2668 1 video battery 10912 0 evdev 9032 0 snd_intel8x0 28120 1 snd_ac97_codec 99912 2 snd_intel8x0m,snd_intel8x0 ac97_bus 1476 1 snd_ac97_codec snd_pcm_oss 35736 0 snd_mixer_oss 15004 1 snd_pcm_oss processor 36332 2 acpi_cpufreq snd_seq_oss 26496 0 snd_seq_midi 6216 0 nsc_ircc 18672 0 snd_rawmidi 19172 1 snd_seq_midi rtc_cmos 10260 0 snd_pcm 65536 5 snd_intel8x0m,snd_intel8x0,snd_ac97_codec,snd_pcm_oss snd_seq_midi_event 6236 2 snd_seq_oss,snd_seq_midi irda 165560 1 nsc_ircc button 5596 0 rtc_core 15764 1 rtc_cmos rtc_lib 2340 1 rtc_core crc_ccitt 1660 1 irda snd_seq 46676 6 snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_seq_midi_event snd_timer 18516 2 snd_pcm,snd_seq snd_seq_device 6284 5 snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_rawmidi,snd_seq shpchp 29480 0 pci_hotplug 25160 1 shpchp snd 51460 12 snd_intel8x0m,snd_intel8x0,snd_ac97_codec,snd_pcm_oss,snd_mixer_oss,snd_seq_oss,snd_rawmidi,snd_pcm,snd_seq,snd_timer,snd_seq_device i2c_i801 8860 0 i2c_core 19204 4 i915,drm,i2c_algo_bit,i2c_i801 soundcore 6104 1 snd snd_page_alloc 8020 3 snd_intel8x0m,snd_intel8x0,snd_pcm intel_agp 25432 1 raid456 48144 0 raid6_pq 80144 1 raid456 async_xor 2744 1 raid456 async_memcpy 1740 1 raid456 async_tx 2860 3 raid456,async_xor,async_memcpy xor 15792 2 raid456,async_xor mmc_block 9880 0 sdhci_pci 7188 0 sdhci 15628 1 sdhci_pci ehci_hcd 32168 0 uhci_hcd 20356 0 mmc_core 47852 2 mmc_block,sdhci led_class 3804 2 thinkpad_acpi,sdhci e1000 109796 0 usbcore 134692 6 usb_storage,usb_libusual,usbhid,ehci_hcd,uhci_hcd thermal 13892 0 fan 4424 0 squashfs 21204 0 Regards, John -- John Magolske http://B79.net/contact -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
