I have found a bug, but I'm not sure it's this one still. Please apply the appended patch on top of the previous one (i.e. the second of my patches) and check if that helps. Thanks, Rafael --- From: Rafael J. Wysocki <rjw@xxxxxxx> Subject: PM / Hibernate: Fix ioctl SNAPSHOT_S2RAM The SNAPSHOT_S2RAM ioctl used for implementing the feature allowing one to suspend to RAM after creating a hibernation image is currently broken, because it doesn't clear the "ready" flag in the struct snapshot_data object handled by it. As a result, the SNAPSHOT_UNFREEZE doesn't work correctly after SNAPSHOT_S2RAM has returned and the user space hibernate task cannot thaw the other processes as appropriate. Make SNAPSHOT_S2RAM clear data->ready to fix this problem. Signed-off-by: Rafael J.
