Hello Rafael,
Yet another patch in the suspend2 feature-set series.
It sets cpufreq to maximum during the cycle.
It is important to finish the process as quickly as possible (human engineer
issue :) )
When running on batteries it may take forever without this...
Please consider to apply.
If you accept this, I will update the HOWTO later.
BTW: It is starting to be very difficult to provide patches without
conflict... This one conflicts with the compress one at Makefile.
Queue:
suspend-lzo.patch
suspend-pciutils.patch
suspend-prefix.patch
suspend-reboot.patch
suspend-cpufreq.patch
Future: fbsplash support.
Best Regards,
Alon Bar-Lev
