I had similar issues. I have tried to upgrade with adept by changing the dapper repositories to edgy and after I got some errors (the ones that .... failed because the commit would break packages). When trying to boot I get instead of the splash screen a string saying something about ACPI checking the acpiid ...etc. and the cursor blinks and nothing happens anymore.
This was on a 64bit installation that I have on my machine. I have not deleted it so if you need any logs I can produce them. I have another 32bit Dapper installation for productivity that works. For now I am sending my sources.list ** Attachment added: "sources.list" http://librarian.launchpad.net/4809819/sources.list -- Upgrade from Dapper to Edgy Eft beta fails https://launchpad.net/bugs/63353 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
