I have this problem from the beginning (more than year now), I already wrote about that on current@ some time ago. The problem is that it appears sporadically (but always in not very suitable moment) and I can't see anything on terminal, so it's hard to debug/complain.

So I just updated to r251845, applied the Konstantin's patch and rebuild world/kernel. Sadly nothing changed this time. I boot into X11, then shut it down from the gnome menu, waiting for 15 minutes of blank screen. Nothing happens. Then doing my everyday procedure: powering it down by pressing a button, then usual full fsck (journaling fails) in single mode and reboot.

My laptop can shutdown after this patch, however I receive the following 
messages:

And I have no that guys in my log files. Only this at booting:

Any suggestions?

Thanks for the patch.
I've adapted the proposed patch for stable/9 and it is running with
SNA enabled now.

In other words, your problem seems to be gone with the patch applied ?

Can you please also create patch for -current?

It is for current. Code in stable/9 should be identical though.
