Common Issues
GNOME session saving broken
link to this item - Bugzilla: 465321 and GNOME Bugzilla: 552387
The GNOME session management subsystem is being completely rewritten (see this page and this page), so this particular feature is in flux right now. This blog entry discusses a helpful workaround.
Xfce Window Manager and Window Manager Tweaks broken
link to this item - Bugzilla: 471927
Due to a gtk2 bug in F10, the Xfce tools for "Window Manager" and "Window Manager Tweaks" may give the following error:
"These settings cannot work with your current window manager (imsetting-xim)"
To work around this issue, run the following command in a terminal, and then restart:
su -c 'yum remove imsettings'
ATI Radeon problems
It is mentioned in the release notes, but you might have overlooked it:
The kernel modesetting drivers for ATI Radeon are still in development and buggy. Some of the issues are tracked on xorg-x11-drv-ati while others are tracked with the kernel.
If you see display-related problems on ATI Radeon then you can try adding nomodeset to the kernel boot prompt in grub or permanently in /etc/grub.conf.
Disabling compiz might also help.
Fedora 10 i686 Xen guest won't boot
link to this item - Bugzilla: 470905
Fedora 10 (i686) must use the kernel-PAE package to run as a Xen guest. The installer fails to choose this kernel when it is being installed under Xen, so the installed system will not boot.
As a workaround, you can use a kickstart file to install kernel-PAE. An updates.img file that fixes this problem should be made available soon.
Error upgrading systems with kernel-xen installed
link to this item - Bugzilla: 472462
If you try to upgrade a system with 
kernel-xen
PackageSackError: No Package Matching kernel
kernel-xen has been removed from Fedora and no upgrade exists in Fedora 10. Xen host services are now provided by kernel-xen from your system and the upgrade will complete normally.
