Hi All, Ever since upgrading to recent kernels on FC4-devel and FC2 I've been experiencing total lockups on two different laptops. The FC2 laptop ran fine until upgrading to the 2.6.10-1.12 kernel (the kernel before that is 2.6.7-something and worked well) and the upgrade was handled using yum. The current 2.6.10-1.14 kernel doesn't even seem to want to boot, but I haven't had a chance too look into this because it's my wife's laptop and she's only just reported it this morning after the upgrade last night. On the FC4-devel laptop, I've been getting similar (the same) lockups using recent kernels. I'm pretty sure the problem isn't in the 2.6.10-1.1143 kernel, but I get is a lot with the 2.6.10-1.1148 kernel and I'm pretty sure it was an issue in the 2.6.10-1.1146 kernel too. These lookups are complete. The mouse and keyboard do not respond at all, the screen doesn't change and you can't ping the box from another machine. The only thing to do is yank the battery and powercord and reboot. Are other noticing this? Rodd
