Comment 16 for bug 539467

i have the same problem but its constant to the point i can't even install lucid most of the time, windows 7 works perfectly so its not a hardware problem, i seen this bug or various hardware and ubuntu versions so i'm thinking the debian/ubuntu has a problem with the way drive access is setup in the kernel, fedora 12 doesn't have this problem.
