Two times I had the rather strange issue that the machine booted freshly instead of resuming! First I thought I maybe didn't wait until the image was saved, before turning the laptop off. But now it happened a second time and also the ThinkPad T42 has a battery in it, thus it should always be able to complete writing the image. For resuming I found this in the syslog: Oct 4 09:19:10 shambhala kernel: end_request: I/O error, dev fd0, sector 0 Oct 4 09:19:10 shambhala kernel: PM: Starting manual resume from disk Oct 4 09:19:10 shambhala kernel: PM: Resume from partition 8:2 Oct 4 09:19:10 shambhala kernel: PM: Checking hibernation image. Oct 4 09:19:10 shambhala kernel: PM: Error -22 checking image file Oct 4 09:19:10 shambhala kernel: PM: Resume from disk failed.

It seems the last log messages prior to hibernating have not fully been written by rsyslog. Whats going on there? I didn't see this with Nigel's patches without the readahead patch. But then now I am testing suspend next + his patches, which may well contain other patches, as far as I understand. Any change to test with some newer state of suspend-next? Rafael did you integrate Nigel's patches in your tree? Ciao, -- Martin 'Helios' Steigerwald - http://www.Lichtvoll.de GPG: 03B0 0D6C 0040 0710 4AFA B82F 991B EAAC A599 84C7
