Hi, Keir This is a small patch for fixing APIC 0x40 error when do onlining offlined CPU or Host S3 resume. disable_APIC_timer actually is not useful here. Actually it will trigger a local APIC error when masking the LVT entry when vector is zero on Intel P6 family. This "APIC error on CPU%d: 00(40)" appears when online the offlined CPU and Host S3 resume. Thanks a lot for your help! Criping
