Comment 36 for bug 901215

Linux q2 3.2.0-29-generic-pae #46-Ubuntu SMP Fri Jul 27 17:25:43 UTC 2012 i686 i686 i386 GNU/Linux

Like Lorenz it stopped again at some point and I have
to blacklist uas. It is 'blacklist uas', not uad. In /etc/modprobe.d/blacklist.conf

With the blacklist on as shown below the Touro mounts again, normally.

My blacklist.conf, part of it, as of a few minutes ago:

# Trying this so Hitachi Touro will be usable.
# Jan 11, 2012. See bug 901215, linux bug.
# Mar 11, still not working if uas present.
# Sometimes fails even if this blacklist command present.
# April 26 giving up on blacklist command it is no help.
# Worked without blacklist for a while.
# Sep 4, 2012 not working, so try blacklist again.
blacklist uas
