Hi Riley, I am not sure if I should have send this bug-report to you. I hope you don't mind. If you do could you send me the correct email adress. Many thanks in advance. Toshio [1.] One line summary of the problem: Reboot command hangs system. [2.] Full description of the problem/report: After I issue the command "reboot" from the prompt the system closes down normally. Then the system says : "Restarting system.. ". The screen becomes black and system hangs. init 0 works correctly system shuts down normally. I already tried possible kernel-parameters : reboot=[c|w],[b|h] Problems only seems to happen on the IBM's I have here. IBM GL300 IBM Aptiva (machine in this BUG-REPORT) The system has the latest patches from RH.
