My bug is not listed
Not every bug is listed in this page, but Bugzilla should be a comprehensive database of known bugs. This page is a sampling of the bugs most commonly discussed on our mailing lists and forums.
To see if your bug has already been reported, you can search Bugzilla. If it has not yet been reported, we encourage you to do so to help improve Fedora for yourself and others. A guide to Bugs and feature requests has been prepared to assist you.
If you believe an already-reported bug report should be added to this page because it is commonly encountered, you can:
- Add it yourself, if you have wiki access. Please follow the style and guidelines explained in the comments in the page source.
- Or, add the CommonBugs keyword to the bug report. Someone from the QA team will then inspect the issue to determine whether the bug should be listed as a common bug. To expedite your request, please add a comment to the bug that includes
- a summary of the problem
- any known workarounds
- an assessment on the impact to Fedora users
For reference, you can query Bugzilla for bugs tagged CommonBugs:

Installation issues
Hardware issues
Systems hangs on X startup with NVIDIA GeForce GTX 580 adapter (affects installation)
link to this item - Bugzilla: #802026
It has been reported that a bug in the nouveau video driver causes systems with an NVIDIA GeForce GTX 580 video adapter to hang as soon as the X graphical environment starts up. This issue also affects installation, so as soon as X is started, installation hangs.
This issue can be worked around by disabling hardware acceleration. To do this, pass the kernel parameter nouveau.noaccel=1. You can append kernel parameters at boot time - of a live image, DVD or network install image, or an installed system - by hitting the Tab key when the system reaches the bootloader menu, and typing in the desired additional parameter.
You can make the workaround 'permanent' on an installed system either by editing it into the /boot/grub2/grub.cfg file, or by creating a file named /etc/modprobe.d/noaccel.conf containing a single line reading:
options nouveau noaccel=1
Software issues
DKMS broken due to executable being named dkms.old instead of dkms
link to this item - Bugzilla: #790521
The 
dkms/sbin/dkms and renames it to /sbin/dkms.old. This appears to have been intended to prevent an old copy of dkms in /sbin from overriding the Fedora-provided copy in /usr/sbin. However, with the /usr move feature in Fedora 17, /sbin is a symlink to /usr/sbin, and consequently the Fedora package itself effectively provides a copy of /sbin/dkms - which its own script promptly renames. The upshot is that there is no 'dkms' executable after installation of Fedora 17's
To work around this issue, manually rename /usr/sbin/dkms.old to /usr/sbin/dkms. You may have to do this after each update of the
We hope to issue an update to resolve this bug shortly.
SELinux deny_ptrace flag on by default: will prevent gdb etc. from working
The SELinux deny_ptrace flag is enabled in Fedora 17. This will prevent applications that use the kernel ptrace(2) API - like gdb and strace, and other debugging utilities - from working: you will see an SELinux denial when trying to use them. To toggle the flag off (until reboot), so you can use a debugger, run setsebool deny_ptrace 0 as root.
Soundcard inaccessible after upgrade from a previous Fedora release
link to this item - Bugzilla: #815413
A few users reported that after upgrading from Fedora 16 their /etc/pam.d/* configuration files did not reference the pam_systemd.so module. As a result, the user login sessions are not properly tracked by the systemd-logind daemon and the users are not granted access to sound and other devices. It is unclear what the exact conditions for the wrong PAM configuration to occur are. The problem does not seem to be easily reproduced. To fix the problem, run authconfig --updateall which will correct the PAM configuration files.
