Sorry, I'm not sure how I can get these informations. Can you please tell me what I should do? I'll continue to dig the issue. I also have the following message. ..MP-BIOS bug: 8254 timer not connected to IO-APIC Kernel panic - not syncing: IO-APIC + timer doesn't work! Try using the 'noapic' kernel parameter It appeared only on 64bit and the 2nd kernel without boot parameter noapic.
