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... Joerg
