The problem with mounting was my fault: I only installed 'linux-image' and not 'linux-image-extra' which contains rpcsec_gss_krb5.ko. That module is needed for mounting with 'sec=krb5'.
So I was able to test 3.8.0-030800rc5-generic from http://kernel.ubuntu.com/~kernel-ppa/mainline. Unfortunately the bug is still there: $ uname -r 3.8.0-030800rc5-generic $ chgrp -v groupname newfile chgrp: changing group of `newfile': Invalid argument failed to change group of `newfile' from groupname to groupname $ chown -v username newfile chown: changing ownership of `newfile': Invalid argument failed to change ownership of `newfile' from username to username -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1101292 Title: NFSv4 regression in 3.4-rc1 causes Invalid Argument on chown/grp To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1101292/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
