hibernation fails from kexec'ed kernel
Hi,
when I try to hibernate and resume from a kexec'ed kernel, the resume fails with:
PM: Image not found (code -22)
I dumped sig and orig_sig from swsusp_check and it looks like this:
53 57 41 50 53 50 41 43 45 32 SWAPSPACE2
53 57 41 50 53 50 41 43 45 32 SWAPSPACE2
So it looks like the image (or only the signature) did not land to the disk.
I use only the in-kernel hibernation, I do not even have the suspend package installed. This is with 3.7.2 and happens this way for some time already. When I boot the kernel normally, hib+resume works just fine.
Any ideas?
thanks,

Note that I see "PM: S|" and the error returned from mark_swapfiles is 0.

Quite frankly, I'm not really surprised, because this is the first time I know of anybody has tested hibernate and resume from a kexec'ed kernel.
I have no idea why exactly it doesn't work, though.
Did you use s2disk or the internal hibernation?

It's quite usual and natural, that people kexec to a new kernel, I think. I used to do that for a long time, but it stopped workign at some point.

I'm trying to debug that ATM...

As I write above, I don't have suspend package installed. This is a pure in-kernel implementation.

I see.
Well, if it used to work and it doesn't any more, then definitely something broke.
The symptom seems to indicate that the image header is in a wrong place.

Or a memory corruption which I saw today (without hibernation) -- data which should have gone to the video memory appeared in struct hid_device :/. I suggest to suspend this thread unless the corruption gets resolved. (I suppose the corruption won't affect this issue, because I haven't ever seen a problem with hibernation unless kexec was used. But who knows...)
