I can not see at what point (on modern systems like Ivy Bridge). On older Core2Duo systems I get a trap 12 in APIC or similar. While I was able to start kernel.old on the modern systems, I fail on both kernel and kernel.old on the C2D system. I'd like to know whether there is a way to save the system I can not reboot the on-disk kernels snce they are, woderfull, compromised. Is there a possible scenario like: a) boot from DVD ROM or USB most recent snapshot b) establish network with on-disk config, svn checkout recent sources into on-disk file hierarchy c) build repaired/patched kernel and install on on-disk (not on the emergency boot media). Thanks, help appreciated and what is about this crash affecting recent CURRENT r270287, what has corrupted the system?
