I reverted to one commit before that, which would be 
eaa959df299157e2640fcb3321537501b6afd9e6
if I am not mistaken. I built and booted that kernel and could reproduce the 
freeze with it (TBH this was not surprising to me, because I originally pinned 
down the problem by bisecting the commits and this commit is after the one 
bisecting found. Am I missing a detail here?)

But strangely enough the freeze this time produced an oops before it locked 
the machine. I couldn't save it to a file but took a picture. The screenshot 
is here:

The oops is _not _reproducable. After a reboot with this same kernel, a 
suspend/resume cycle and some I/O the machine locks again without showing the 
oops.
