Public bug reported: OS: Ubuntu 12.04 x86_64, Hardware: Lenovo T410s (using Intel graphics), i5-540 M.
When running pm-hibernate, and when according to "free" the RAM occupation is below the swap size, hibernation does not take place. When running subsequently "cpufreq-info", only one thread shows up (there should be 4). To put the CPU into its "normal" state requires a reboot. A partial fix: executing (as root): sync; echo 3 > /proc/sys/vm/drop_caches sync; echo 0 > /proc/sys/vm/drop_caches cat /proc/sys/vm/drop_caches frees memory. A subsequent hibernation (with "pm-hibernate") then works. Thank you, François P.
