Hi, I have been using CenOS-4.1 quite sometime now on this laptop. Under CentOS I am having a problem during boots (soft or hard boots) that I never had with any other Linux distros. I have to reboot the laptop twice as the first boot returns blank screen and hangs when it attempts to bring up login screen. I tested this a few times, there is no disk activity or any sign of OS activity.. In the end I switch the laptop off and start again.. It works fine perfectly in the second boot. Not sure what happens in the first boot (though all startup processes return OK till it gets hung) How can I diagnose this problem..? Is this a known problem..? Is there any workarounds..etc ?
