Hi.

Yes, sorry I wasn't able to be there. Some of us don't do this for a job :>

Interesting comment on saving the image in parts: that's precisely what Suspend2 does: LRU pages are saved in part 1 and the rest of the kernel in another.

For what it's worth, recent changes to Suspend2 address some of the issues that were raised: the freezer has been rewritten to freeze userspace prior to kernel space (Pavel's suggestion), and that means that the intrusiveness of the patch has greatly reduced.

Once Patrick and Pavel have finised merging, I intend to work on getting Suspend2 merged in as well. Preparation for that is being done now, including breaking the code up into parts.

Regards,

Nigel
