I've run Fedora for a long time. I stuck with Fedora 14 for a long time as I much preferred Gnome 2 over Gnome 3 and everything just worked. Rock solid.
Since F14 went EOL, I've recently upgraded to F16, but I've been dogged by a couple of stability issues. The rest I've figured out.
Main one is that the system won't always boot. Boot process will continue until it's time for drm/modesetting to take place at which point instead of getting the resized text, I get a blank screen. Adding radeon.agpmode=-1 seems to make this more reliable, but still occasionally hangs.
The system is still responsive - a Ctrl-Alt-Del will reboot the system.
Looking at the logs after the reboot shows nothing - so it's obviously gotten stuck pretty early in the boot process.
How can I debug this issue so that I might gather information to file a bug report?
Second issue is that the system is now completely unstable with AMD Cool'n'Quiet enabled. Already filed a bug for that one. https://bugzilla.redhat.com/show_bug.cgi?id=795334 Sucks to waste electricity when not needed!
