I have the same issue on my two machines: a custom AMD 2.8 GHz desktop box with an ATI radeon rv 100 card and a Dell D610 laptop with an intel i915 video chip.
These two machines run edgy and this issue appears with edgy. The desktop box switch from dapper to edgy was done some months ago. I've upgraded the latop from dapper to edgy yesterday. -- text console garbled from boot up https://launchpad.net/bugs/63970 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
