[TuxOnIce-devel] Back to BFS+TOI issue

I mailed Con Kolivas about TOI+BFS issue and he answered that won't fix
it as BFS is written to get mainline hibernation work but not TOI. He is
surprised that BFS+TOI works *somehow*.
The only quote about technical reason is:
"I suspect that something to do with the way the
compression threads are woken up on resume is broken when run on BFS."
So the last hope is Nigel.
As BFS+TOI users community is large enough, I expect it to help solving
the issue at least by providing debug info. We really need these
3rd-party patches work together.
For now, I discovered that LZO fails as well as LZF does, but with
In case of LZF it fails at tuxonice_compress.c:257 (outlen != PAGE_SIZE).
In case of LZO it fails at tuxonice_compress.c:254 (ret), and also at
tuxonice_io.c:645 (io_pageset == 1).
So crypto_comp_decompress call at tuxonice_compress.c:245 fails. Why —
no idea. I cannot investigate it deeper because of lack of knowledge
about kernel internals.
Nigel, help us if you can. Hope you HDDs are up and spinning .
