Below is the statement that triggers the oops: if (GET_APIC_ID(apic_read(APIC_ID)) != boot_cpu_physical_apicid) BUG(); This occurs both with Hyper-Threading on and off in the BIOS, and with CONFIG_PENTIUMIII and CONFIG_PENTIUM4. Note that 2.4.x kernels boot fine. /proc/cpuinfo is below. Please cc: me on replies.
