Installation issues
UEFI install fails with BootLoaderError: failed to set new efi boot target
link to this item - Bugzilla: #949786
Some UEFI-native installations of Fedora 19 Beta may fail near the end of installation, with the error BootLoaderError: failed to set new efi boot target (or a similar error).
Systems with UEFI firmwares contain a small amount of NVRAM (non-volatile RAM) storage, into which certain UEFI configuration and other data can be written by the firmware or by UEFI-native operating systems. This error usually indicates that the kernel considers the NVRAM storage area to be full, and is refusing to write anything to it when the Fedora installer attempts to write an EFI boot manager entry for the newly installed Fedora system.
In Fedora 19 Beta (in fact, in all recent kernel builds - this behaviour is not specific to Fedora, though it is very new), the kernel attempts not to write to the NVRAM storage when doing so may trigger the recently-publicised bug in some Samsung firmwares, which causes the system firmware to fail if the NVRAM storage is more than 50% full. There are cases where this can interact badly with firmwares that do not do garbage collection very well, and you may therefore be affected by this problem even if your NVRAM storage area is not full and you do not use one of the affected Samsung firmwares. You may also, of course, actually have a full NVRAM storage area.
If you are affected by this problem, there are several things you can try. The Fedora 19 Beta installer attempts to delete non-essential data from the NVRAM prior to writing a boot manager entry. However, it cannot force the firmware to do garbage collection after requesting the deletion. In some cases, several reboots may be required to trigger garbage collection. So the first thing to try if you are affected by this is to reboot the system several times, and then re-try the installation.
If that does not help, you may try resetting the firmware to defaults, or updating or reinstalling the firmware. However, note that doing so can reset the EFI boot manager to its default state, which may remove entries for any UEFI native operating systems you have installed!
If all else fails, you may be forced to install Fedora 19 Beta in BIOS emulation mode rather than UEFI native mode.
We will continue to work on this issue to see if we can improve the situation in any way for the Final release.
Note for journalists: this issue has nothing at all to do with Secure Boot. Please be careful in distinguishing Secure Boot from UEFI.
Bootloader password is required on each boot
link to this item - Bugzilla: #840160
If you set a bootloader password during installation of Fedora 19 (which is only possible when doing a kickstart-based install), the password will be required at each boot of the system. This is a change in behaviour from Fedora 15 and earlier, where the password was required only to change settings from within the bootloader.
Lawrence Lowe suggests that the --unrestricted parameter can be added to menuentry lines in the grub config file to make them available without the password being entered.
Upgrade issues
System hangs at the end of the process when upgrading to Fedora 19 with fedup
link to this item - Bugzilla: #957783
When upgrading to Fedora 19 using the recommended FedUp method, the system may hang at the end of the upgrade process, whereas it should automatically reboot into the upgraded system. The upgrade process has been completed at this point, and it is safe simply to force a reboot at this point. Barring unrelated issues, the upgraded system will be in place and working.
Hardware issues
Boot hangs when using NVIDIA discrete graphics on some Thinkpad models (W520, T420)
link to this item - Bugzilla: #752613 Kernel bugzilla: #43054
Multiple testers have reported that various Thinkpad models - including at least the W520 and T420 - that have hybrid Intel/NVIDIA graphics will fail to boot Fedora 19 when using the discrete NVIDIA graphics adapter. Using the onboard Intel adapter, Fedora will boot successfully.
Further testing indicates that this bug is an interaction between several features of these systems and of Fedora: the VT-d advanced virtualization feature, the X2APIC level APIC, and the NVIDIA adapter. If all three of these things are used together, boot fails. If any one is removed from the equation, boot succeeds.
So if you are affected by this bug, you can choose to boot with any two of those things, but not all three together. You can disable the VT-d feature and select which graphics adapter to use through the system firmware. You can disable X2APIC functionality by passing the kernel parameter nox2apic. In this way, you should be able to determine which of the features you want to use.
The kernel developers plan to address this issue in a future kernel update by blacklisting X2APIC functionality on affected systems, when the NVIDIA adapter is in use.
Software issues
GDM and GNOME render incorrectly on older systems
link to this item - Bugzilla: #909473
Some testing has indicated that Fedora 19's llvmpipe-based software 3D rendering does not work properly on older CPUs (those without SSE2 or equivalent instructions; SSE2 was introduced by Intel with the Pentium 4 in 2001, and AMD added support for it with the introduction of the Opteron and Athlon 64 lines in 2003). If your graphics card is not sufficient for GNOME 3 - which may well be the case on older machines - Fedora will try and use software rendering to display GDM and GNOME, but due to this bug, it may fail entirely or render incorrectly. GNOME 3.8, as included in Fedora 19, no longer has a non-accelerated 'fallback mode' for use on systems where 3D acceleration does not work correctly.
At present the only workaround for this problem is to use a non-3D accelerated login manager and desktop. KDM is probably the most robust alternative login manager. The KDE, Xfce, LXDE and MATE desktops all work without 3D acceleration and would be possible alternatives to GNOME.
"Updates available" notification runs online updater
link to this item - Bugzilla: #863592
Fedora 18 introduced a feature called offline system updates. Its description suggests that 'offline' updates - updates performed across a system reboot - are now the default method for graphical updating in Fedora 18, at least when using GNOME. However, the feature's implementation is still somewhat incomplete: GNOME will still pop up notifications of available updates, and if you click on these notifications as you are encouraged to do, the 'online' update process (updates installed within the running system) will be launched.
This is not a major bug - the online update system still works, and while there are valid reasons why offline updates are slightly more robust, online updates are what Fedora used from Fedora Core 1 through Fedora 17 so there is no pressing reason to believe the use of online updates will be a disaster. Both mechanisms perform as intended in Fedora 19, and you can use the online update mechanism as safely in Fedora 19 as you ever did in a previous Fedora release. This note is included simply to explain the situation, in case you are confused as to what's going on.
If you want to trigger an offline update, use the "Install Updates and Restart" entry on the User menu.
