The following question is not getting any further feedback after revisions. Also, it appears to be a - non Ubuntu related - hardware issue. I didn't get any Ubuntu related search hits with the error messages:
Ubuntu 12.04 System crashes right after login - Boot-Repair log included
Can I request a moderator to transfer the question to StackExchange "Super User"? How does this work, just send a message to a user listed as moderator?
