I'm currently running with SLUB again but with /sys/kernel/slab/*/cpu_partial all set to "0" (affecting ~250 files). The box is running for some hours now and pretty loaded with both CPU and disk i/o (load 6-7, which is pretty high for this machine) and it did not oops yet. Looks like setting cpu_partial to 0 does make a difference.
