Interesting :-) -EACCESS makes me suspect that maybe 'mode' 'uid' or 'gid'
mount options are wrong. Of course we would still need to understand if/
why this patch changes the settings.

Can you paste the output of following commands: (both in success and failure
cases).

	$ grep devpts /proc/mounts

	$ ls -al /dev/pts

	$ stat /dev/ptmx

Also, is CONFIG_DEVPTS_MULTIPLE_INSTANCES set in your .config ?

With this patch, does gnome-terminal run when logged in as root ?

Thanks,

Sukadev
