Kernel: 2.4.22-1.2140.nptl NFS configuration: fedora m/c mounts rh9 nfs mount. N/w Configuradtion: Fedora m/c with Linksys wireless & rh9 with director network ethernet connection. Manual umount works fine. Only during shutdown process it hangs. If I take my linksys card out at that moment it just goes to sleep smoothly. May be it has something to do with bug 100920. But I am not sure from where I am. any help will be greatly appreciated. Thanks Raghu.
