I do not use TOI since quite some time anymore since I had some issues=20
with it I do not remember anymore, I think it didn=C2=B4t work reliably=
 back=20
then. I like to try again, but did not come around to do it.

I use in-kernel-suspend, now with 3.0, debian packaged, thus not even s=
elf=20
compiled anymore, and its just rock solid on the T23. Its not that rock=
=20
solide on my new ThinkPad T520, but that might also be some driver issu=
es=20
and I do not use BTRFS on the new one, only on the T23.

Ciao,
