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
<suspend-to-disk... resume>
and get the below dmesg. Oh well, I need to go stare at this when I get
a chance.
