Wysocki" Cc: Andre Przywara , cpufreq@vger.kernel.org, lkml Hi, anyone seen this already? I've got this this morning when resuming and this is -rc4+ (+ tip/master) but without any other cpufreq and powernow-k8 patches. It says below "[last unloaded: acpi_cpufreq]" because I played with loading and unloading powernow-k8 and acpi-cpufreq yesterday but ... Oh, ok, I think I know how it happens: just did a quick test: $ rmmod acpi-cpufreq $ modprobe powernow-k8 and get the below dmesg. Oh well, I need to go stare at this when I get a chance. [48790.833251] powernow-k8: this CPU is not supported anymore, using acpi-cpufreq instead.
