Suspend to RAM deemed stable
I have been running 2.6.12 for quite a while now on my IBM X31 laptop. I came to realize that since 2.6.10, the stability had improved quite nicely.

There are still some nasty and intermittent crashes with suspend, xorg and dualhead that I cannot seem to reproduce in a sane way, but since I've not used dualhead in quite a while, it's not much a problem these days.
