Description Shayin C K 2007-12-23 21:04:23 EST
Description of problem:

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.Whenever I try to open Firefox from clicking a link in email in Thunderbird
Actual results:
SELinux denies access to modprobe:
    SELinux is preventing /sbin/modprobe (insmod_t) "sys_nice" to <Unknown>

Detailed Description
    SELinux denied access requested by /sbin/modprobe. It is not expected that
    this access is required by /sbin/modprobe and this access may signal an
    intrusion attempt. It is also possible that the specific version or
    configuration of the application is causing it to require additional access.

Allowing Access
    You can generate a local policy module to allow this access - see
    http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385 Or you can disable
    SELinux protection altogether. Disabling SELinux protection is not
    recommended. Please file a http://bugzilla.redhat.com/bugzilla/enter_bug.cgi
    against this package.
