I'm quite confident it's specific to bluetooth, because I only need to turn
the bluetooth user space off, most importantly hcid, to make the problem go
away even without the patch (that is, without the patch I don't even have to
uload btusb before suspend if the bluetoot user land is not running).

Is that really necessary?

I can do that, but first I'll check if 2.6.26 is fine.
