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
