> Do you have any power saving settings turned on in the bios? This is a dell computer and it has a power managment option in BIOS. However, I changed it to not-to-save energy mode. After this, I found that the computer restarts rather than hanging. =========================================================== AN ERROR IS SHOWING UP AT BOOT TIME. It seems to be a BUG: ============================================================ Memory for crash kernel (0x0 to 0x0) notwithin permissible range ..MP-BIOS bug: 8254 timer not connected to IO-APIC Red Hat nash version 5.1.19.6 starting Welcome to CentOS release 5 (Final) .... ..... and continues normal booting. Any idea how to deal with it. Please not that it has 4 CPUs. Thanks a lot, - Chandra _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
