I installed FC9 on my system and it shutdown and rebooted without problem under kernel 2.6.25-14.fc9.i686. I updated the kernel to 18.104.22.168-45.fc9.i686 and not I cannot reboot or shutdown properly. The system hangs at "Sending all processes the KILL signal...", it was hanging at "Unmounting file systems". A Crtl-Alt-Del gives "init: RC6 main process killed by TERM signal", the system still does not reboot.
All of this works properly under 2.6.25-14.fc9.i686.
Any advice on how to fix this would be appreciated.
