Description of problem: A PC with Intel Pentium 4 2.8GH HT hangs on startup if using smp kernel. (it did it with FC2 too, but not with RH90) After a few services are started (around starting cups but not always the same) the system hangs forever. Version-Release number of selected component (if applicable): Fedora Core 3 with all latest packages updates How reproducible: maybe with a same processor. Steps to Reproduce: 1. Install FC2 or FC3 on a HT processor 2. Boot with a SMP Kernel 3. Actual results: I have tried to upgrade to the new kernel released but no solution. Actually using non smp kernel Expected results: Additional info:
solved adding acpi=ht in kernel parameters and disabling PNP/OS into BIOS
