Yes I know, I answer to myself :-o, but it's just to add more info on swsusp beta16 ... - I can suspend my laptop (Presario 2800) without any difficulties using /proc/sys/kernel/swsusp interface. - "echo 4 > /proc/acpi/sleep" still doen't works, but it seems to be a Pressario 2800 issue (acpi has never really worked on it). - I can't resume after shutdown, I have the following message when the RAM image is been recovered: alloc pages: 0-order allocation failed [gfp=0x3d2/0] - I've found on Mandrake's expert mailing list that other people may have the same problem with the following config : "Mandrake 9.0, cooker kernel-2.4.20-2mdk and swsusp beta 16, Sony Vaio VX88 with i810 chipset."
