Exiting from X either via ctrl-alt-backspace or the "logout" menu, causes X to hang.... The led on the monitor that indicates that it is receiveing video signals goes from green to orange indicating that it is no longer receiving any video signal. I can ssh to the machine from another machine and open a xterm and everything looks ok.... X isn't running though. (X had been started from the console via "startx" and I couldn't switch back to the console via ctrl-alt-f1.) The first time I tried rebooting the system via "shutdown -rf now", which just hung the xterm so I opened another xterm via ssh, killed the shutdown and old ssh processes and did /sbin/init 6 which worked and the system rebooted. The second time, "shutdown -rf now" worked and the system rebooted. (Video card is a Permedia 2 PCI. MB is a IWill DBL100, with a single 400MHz PII and 128MB.) The system had been running RH 6.1 without any problems. I just rebooted, did startx again, waited for gnome to start up and then did ctrl-alt-f1. The same thing happens.... ie X hangs just like in the other cases. (As long as I don't try to leav X, things seem to work ok. I was able to edit a couple of files with emacs and open a couple of nxterms.)
were you having problems with XFree86 3.3.5 / Red Hat 6.1?
This is the same as part 1 of bug 7597... which has been marked as a duplicate of the **TOP SECRET** bug 8789... It's not X crashing, it's the FrameBuffer text mode that's broken on the Permedia 2.
