the vendor_id: 0x8086 seems to be Intel
device_id: 0000:00:00.0 seems to be the host bridge/root complex
So basically, you have an hardware error, that is most likely located at the northbridge. It could be a CPU, memory or motherboard issue, contact the hardware vendor for support. Also worth a shot, is microcode and BIOS (motherboard & IPMI) updates.
