Maybe by chance a BIOS upgrade will be ok. If that's not the case, or BIOS is alredy the newest, we could resolve that issue by hardcoding sane values under the powernow driver, or by rewritting the DSDT of this laptop. The second solution will give you the oportunity to not have to patch powernow for each upgrades. > device_attach: powernow0 attach returned 6 > > "/etc/rc.d/powerd start" brings > > powerd: lookup freq: No such file or directory > > Are there any chances to get a working cpufreq-mechanism on that machine? > > Here you can find the dmesg output: > > * <http://daemon.crashmail.de/~stell/paradise_dmesg.txt>; > > And a complete lists of all sysctls: > > * <http://daemon.crashmail.de/~stell/paradise_sysctl.txt>; > very litte hw.acpi.*, hum?
