 Not yet. I scanned through the diffs between 2014-07-31 to 2014-08-08 (I 
 hope the culprit is in there at that time).
 There was not much relating ARM. but I saw an ARMV6 related item for a 
 speculation (though I have not scanned for any impact):

 But that is just a wild guess,
 It happens on different RPIs with different cards (16Gb and 32Gb). Older 
 kernels run fine for now 18d with a kernel from July 31st.
 I have not started bisecting it as the test takes > 20h per iteration.
 Maybe we need to go through that if nothing else springs to mind.
 The strange thing is, that it takes so long and I could not trigger it 
 earlier by running 'find / -ls' over and over.
