Unter Windows habe ich noch nähere Informationen zu dem System ermittelt: Es ist ein Pentium M 1.5 Ghz (Banias) mit Intel Centrino. Einem Logfile Eintrag konnte ich noch entnehmen, dass es bei aktiviertem speedstep_centrino Modul sporadisch zu Kernel Oops kommt. Hier habe ich einen davon aus /var/log/messages Apr 30 16:02:04 linux kernel: ACPI: AC Adapter [ADP1] (on-line) Apr 30 16:02:04 linux kernel: ACPI: Battery Slot [BAT1] (battery present) Apr 30 16:02:05 linux kernel: ACPI: Power Button (FF) [PWRF] Apr 30 16:02:05 linux kernel: ACPI: Lid Switch [LID0] Apr 30 16:02:05 linux kernel: ACPI: Sleep Button (CM) [SLPB] Apr 30 16:02:05 linux kernel: drivers/usb/serial/usb-serial.c: USB Serial support registered for Generic Apr 30 16:02:05 linux kernel: usbcore: registered new driver usbserial_generic Apr 30 16:02:05 linux kernel: usbcore: registered new driver usbserial Apr 30 16:02:05 linux kernel: drivers/usb/serial/usb-serial.c: USB Serial Driver core v2.0 Apr 30 16:02:05 linux kernel: ACPI: CPU0 (power states: C1[C2] C2[C3]) Apr 30 16:02:05 linux kernel: ACPI: Processor [CPU1] (supports 8 throttling states) Apr 30 16:02:05 linux kernel: ACPI-0400: *** Warning: Invalid active threshold [0] Apr 30 16:02:05 linux kernel: ACPI: Thermal Zone [THRM] (48 C) Apr 30 16:02:06 linux kernel: ACPI-0294: *** Error: Looking up [ACST] in namespace, AE_ALREADY_EXISTS Apr 30 16:02:06 linux kernel: ACPI-0601: *** Warning: During name lookup/catalog, AE_ALREADY_EXISTS Apr 30 16:02:06 linux kernel: ACPI-1140: *** Error: Method execution failed [\_PR_.CPU1._PDC] (Node dffcef40), AE_ALREADY_EXISTS Apr 30 16:02:06 linux rcpowersaved: enter 'speedstep_centrino' into POWERSAVE_CPUFREQD_MODULE in /etc/sysconfig/powersave/cpufreq.
