You have been subscribed to a public bug:

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. Rotzinger
