[Bug 445852] Re: SSD stall during boot

[Jim]

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
