Tried with TREE_RCU, unfortunately the problem persists. However, the OOM 
messages did not make it to the disk this time. Syslog continued to work 
until 11:51 (local time), the slabinfo-8-TREE_RCU.txt file was written to 
until 11:57, the machine was already unusable at that point. At 12:07 I 
took a "screenshot" and then powercycled the machine:

  http://nerdbynature.de/bits/2.6.39-rc4/oom/
  (The files marked with -8 are the current ones)

Btw, the xfs filesystem I'm du'ing over is still mounted with "noatime".

Any ideas? Patches to try?

Thanks,
Christian.
