>Summary
>    SELinux is preventing /usr/sbin/rpc.mountd (nfsd_t) "getattr" access to
>    device /dev/dmmidi.
>
>Detailed Description
>    SELinux has denied the /usr/sbin/rpc.mountd (nfsd_t) "getattr" access to
>    device /dev/dmmidi. /dev/dmmidi is mislabeled, this device has the default
>    label of the /dev directory, which should not happen.  All Character and/or
>    Block Devices should have a label. You can attempt to change the label of
>    the file using restorecon -v /dev/dmmidi. If this device remains labeled
>    device_t, then this is a bug in SELinux policy. Please file a
>    http://bugzilla.redhat.com/bugzilla/enter_bug.cgi against the selinux-policy
>    package. If you look at the other similar devices labels, ls -lZ
>    /dev/SIMILAR, and find a type that would work for /dev/dmmidi, you can use
>    chcon -t SIMILAR_TYPE /dev/dmmidi, If this fixes the problem, you can make
>    this permanent by executing semanage fcontext -a -t SIMILAR_TYPE /dev/dmmidi
>    If the restorecon changes the context, this indicates that the application
>    that created the device, created it without using SELinux APIs.  If you can
>    figure out which application created the device, please file a
>    http://bugzilla.redhat.com/bugzilla/enter_bug.cgi against this application.
>
>Allowing Access
>    Attempt restorecon -v /dev/dmmidi or chcon -t SIMILAR_TYPE /dev/dmmidi
