After many, many reboots and kernel recompiles i can hibernate 🙂

It appears that it is an ACPI problem, but if a use a hdparm like this for my disk
[b]hdparm -d 1 -A 1 -m 16 -u 1 -a 64 /dev/hda[/b]

IT WORKS.

Probably that i can read from the disk fast before an ACPI event, i don’t know.

I haven’t test it yet with laptop mode, but at least it works without any problems so far.
