Description my_linux 2011-06-11 18:38:25 UTC
SELinux is preventing /usr/libexec/gnome-session-check-accelerated-helper from read, write access on the chr_file card0.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that gnome-session-check-accelerated-helper should be allowed read write access on the card0 chr_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep gnome-session-c /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
