I thought that the kernel had support for that, maybe that is dependent on your machine...

It will ignore it (and vice versa). They both write a sightly different signature on disk. > - on my machine, resume is unable to read the image and prints a huge > message.

Hmm, that is a bit disappointing, I had hoped suspend was written clean enough that it would run on powerpc too... I don't have that much experience with powerpc, but they are big-endian, right? Judging from what message your get it is mostly likely failing in init_swap_reader, but that is just a guess. It would help if you could pinpoint where resume fails. It is not that much code, so if you feel like it, maybe you could add some printfs;) I'm adding the suspend-devel list to cc, maybe rafeal or pavel have some idea what is most likely to fail on powerpc? grts Tim ------------------------------------------------------------------------- Take Surveys.
