Hello, I just tried to boot 3.7 and it ends in an APIC panic. I tried to use the recommended "apic=debug", but that does not change anything in the output, at least not in the visible part. The last known kernel to boot was 3.5. If it matters I can try to boot 3.6. Also, the recommended "noapic" option makes it boot a little bit further, but then ahci does not work properly and fails to detect hard disks. Attached is a photo from the failure and dmesg with 3.4.7. Cheers, BErnd
