No, I am not using NFSv4 on the box where the BUG happens. I have
another box mounting the same directory where the BUG does not trigger
with v3.6-rc1. A difference I spotted between the kernels is, that on
the failing box NFS is compiled as a module whereas it is compiled into
the kernel on the box that works fine. Not sure if that has anything to
do with the problem...
