Please elaborate: What does "This" in "This was not the case before." refer to? The "Could not enable APIC!" boot message or the XT-PIC in /proc/interrupts? 2.4.10 merged code from 2.4-ac which (in some .configs) will attempt to enable the CPU's local APIC. The boot message above is printed if your CPU doesn't have one. >Anyone have any ideas why this is? The APIC stuff was getting detected >fine in 2.4.7. Can you send me your .configs and boot logs for both 2.4.7 and 2.4.10? I don't think there is an actual problem, but I'd like to make sure. /Mikael
