Two times I had the rather strange issue that the machine booted freshly=20 instead of resuming! First I thought I maybe didn't wait until the image=20 was saved, before turning the laptop off. But now it happened a second time= =20 and also the ThinkPad T42 has a battery in it, thus it should always be=20 able to complete writing the image. =46or resuming I found this in the syslog: Oct 4 09:19:10 shambhala kernel: end_request: I/O error, dev fd0, sector=20 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.

It seems the last log messages prior to hibernating= =20 have not fully been written by rsyslog. Whats going on there? I didn't see this with Nigel's patches without the=20 readahead patch. But then now I am testing suspend next + his patches,=20 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?
