Hi Bernd,

Your patching for d_rehash() for your servers? I thought the race 
conditions which causes the softlockup only happened on the patchless 
clients (which were running).
The solution I saw was run lustre supplied kernel or run the iopen-misc 
patch on the kernel.

Or did you mean you are already patched?
