Using the mainline kernel git describe == v2.6.32-rc8-259-g2127816),

==============================
I do not know if this is a regression, as I just recently tried hibernation.
The system has x86_64 architecture. The source is "dirty" due to a local
modification of the rtl8187 driver, which is not even loaded.
If additional info is needed, please ask.
