I'm currently in the process of analysing what is happening inside gssd during these operations. I'll get back later with a summary of my findings. However, I have found a real bug this time. An honest to FSM kernel crash. This is how I reproduced it: - Kill gssd - Attempt to mount a kerberised NFS mount from the Linux machine - The mount attempt will hang because gssd isn't running - While the mount is hung, start gssd - Kernel crash What should I do about that one?
