Comment 45 for bug 445852

Reproduced on a stock eeepc 900 linux version, installing karmic to the 4G ssd. (I did a dist-upgrade from jaunty, which works fine) Also, I have gotten many cases where I needed to overwrite the disk with zeros to make it usable again. (this happens after one or two boots with karmic, I then reinstall to try to fix it)

kernel is 2.6.31-14-generic

dmesg |grep ata2 gives me
