Never boot a different kernel then the one you suspended with. Unless you know what you're doing of course, in which case you would have invalidated the image yourself. Maybe we need bigger warnings about that. > - reboot > - boot 2.6.18-3-686 again > ... the suspended image is detected and uswsusp tries to resume. > > At this point I frantically pushed the power button and didn't wait for > possible checks done after image is loaded. > If there are any checks on eg. last mount times and mount counts of > filesystems that were in use, that are done _after_ the image is > loaded, the bug can be downgraded.

I don't agree with you here. This scenario is not likely (impossible) to occur if you just install uswsusp and the debian kernels. FWIW, this problem is shared between all three suspend implementations, also the (non-uswsusp) in kernel one. I do agree it would be nice to have a script in the boot-up sequence that would invalidate a suspended image. The hibernate package has a script that does just that. Maybe I should copy it to here to, grts Tim
