Package: nfs-common
Version: 1:1.2.6-3
Severity: normal
Mounting a kerberos-protected nfs4 export is unsuccsessfull on powerpcspe. nfs-common initializes without error, and rpc.gssd appears to be running. Upon a mount attempt, the following error message was displayed:
mount: fstab path: "/etc/fstab"
mount: mtab path: "/etc/mtab"
mount: lock path: "/etc/mtab~"
mount: temp path: "/etc/mtab.tmp"
mount: UID: 0

mount: external mount: argv[1] = "nfsserver:/home/yesterday"
mount: external mount: argv[2] = "/home"
mount: external mount: argv[3] = "-v"
mount: external mount: argv[4] = "-o"

After this message, rpc.gssd is no longer running. Further mount
attempts timeout with the following:

I have not verified this as a problem with the same package versions on
any other architecture, but I suspect this is an architecture specific
problem.
