Description of problem: I just did a yum update. Rebooted. When the Xorg server starts, the system freezes (not even reachable over the net, so I assume it's a panic although there's nothing to see on the laptop display as it had just blanked for the Xorg server startup). Version-Release number of selected component (if applicable): kernel-2.6.17.1-2139_FC5 How reproducible: Do a yum -y update (today:-). Old and new rpmpkgs lists will be attached. Steps to Reproduce: 1. install kernel-2.6.17 RPM and reboot 2. startx Actual results: Screen blanks. Systems freezes. Not reachable on the network. Expected results: Uhh, a login screen:-) Additional info: I at first suspected the updated Xorg RPMs but it turns out the difference is the 2.6.17 kernel. Reboot with kernel-2.6.16-1.2133_FC5 and Xorg starts up just fine. I googled 2.6.17 and there's some chatter between Linus and others about "X being broken again" caused by changes to DRM in 2.6.17.

same here. on my Toshiba M40 with ATI M300. I see lots of ACPI errors in dmesg if I boot at runlevel 3. going to level5 or doing startx freezes the PC.
Appears to be working now when updating to kernel-2.6.17-1.2157_FC5 and xorg-x11-drv-ati-6.5.8.0-1 (not sure if it was the new kernel or new ati drivers or both, but they both showed up with the most recent yum upgrade).
