So, I've done a partial bisection, the breakage appears to have 
gone upstream between v3.8-rc3 and v3.8-rc4.

This roughly coincides with the time frame when I first saw 
these lockups pop up, so in that sense it's a plausible result - 
but there weren't all that many commits in -rc4 and none looks 
really suspicious, so this might be one of those non-bisectable 
bugs.

( Later today I'll try to finish the bisection just in case it
  results in something useful. )

Thanks,

	Ingo
