Comment 38 for bug 539467

Please note that bug 528981 is in regards to a PATA controller. But yes, the problem has been fixed in 2.6.33+. The problem didn't manifest itself until sometime after 2.6.28, and by the time Karmic rolled around it was impossible to even complete an installation without such severe corruption that the installation failed. The default Lucid kernel is markedly better, but still will result in corruption.
