However, for the last couple > of weeks I've been unable to reproduce it. We have the problem with nfs-root. From the kernel command line: root=/dev/nfs nfsroot=192.168.23.2:/home/mkl/pengutronix/xxx/bsp/OSELAS.BSP-xxx-Grabowski-trunk/platform-Ronetix-PM9263/root,v3,tcp /home/mkl/pengutronix is a link which points to a link /ptx/work/octopus/mkl (which is a ext3-based) which points to WORK_1/mkl which is also ext3-based. The server is 2.6.32 and has been rebooted yesterday :), nfs-utils are 1.2.2. I make a tcpdump if needed.
