Okay... thats solved now.
Conclusions:
1) There was no XFS problem as the sync I added at the beginning of my pre hibernate script did avoid the truncated files the one time I still had the hang. Thus those appear to have been IO in flight.
2) Its not MTRR_SANITIZER as explained above nor any other mainline problem.
3) Instead problems gone, when I replaced the inofficial TuxOnIce rc7a for 2.6.26 to 2.6.27 forward port patch I used[1] with the official but still not officially released current tuxonice for 2.6.27 patch[2].
So sorry for the noise. I just learned to prefer official upstream patches. Whether they'd be officially released or not. Can ask whether they appear to be stable before trying one. ;)
