I can't seem to have this distro run on my machine for more than a few hours without my system hanging or the kernel crashing.
The biggest culprit seems to be the PackageKit, which is indeed a nightmarish application. But the whole distro also seems to be built on strange grounds.
For instance, upgrading to X.org 1.5 from the main repository invalidates the fedora boot screen (a quiet attractive one, at that). This is no big deal, the OS keeps booting in text mode and Gnome fires normally. However, this issue runs across all machines, regardless of setup, after the update. So why did someone have to fill a bug report for an issue that happens on any fedora machina and regarding a package on the main repository? Scary...
I should stay away from this, shouldn't I?
