I can't answer that one; sorry. I just know it's fixed inMint 10, cause it
came up on my system the other day, took like maybe 3 to 5 minutes at the
most. Then it finished booting. I tried Ubuntu 10.10, before Mint 10 RC came
out. If I'm not mistaken Ubuntu still has the same problem.lol Mint's just
an awsome distro, you can't do better than mint.
