Hi There, Sorry - my last post was a little vauge before... There is a bit more info: I have installed FC5 on my Tecra A6 laptop, everything installed correctly, but on boot - it first sets the clock, then stalls at 'udev'. After doing some digging in this forum, i have tried various things but am still having problems. I have changed the default value of udev_log from "err" to "info" in /etc/udev/udev.conf. This now shows where udev gets, which is: udevd_event[1004]: udev_event_run: seq 582 finished If i add "noacpi MEM=512M" to the linux kernel line in grub, then it hangs here: udevd_event[960]: run_program: '/sbin/modprobe' returned with status 0 udevd_event[960]: pass_env_to_socket: passed -1 bytes to socket '/org/kernel/udev/monitor' (I have have tryed commenting out "ACTION=="add", SUBSYSTEM=="?*", ENV{MODALIAS}=="?*", RUN+="/sbin/modprobe $env{MODALIAS}"" from the /etc/udev/rules.d/50-udev.rule file as suggested elsewhere in this forum) Note: This laptop has a ATI Raedon card and a Intel Core Duo processor. Any help/suggestions are most appreciated. Regards, Simon
