Public bug reported:
Reference is made to Bug #772273 previously reported (from Ubunti
11.04).
I am using a Lenovo laptop with a SSD installed (specifically OCZ Vertex III,
but this is not really interesting, I believe).
dmesg is full of messages saying "ata1.00: head unload failed!", which seems to
be caused by hdapsd is triggered by Lenovo's gravitational sensor, hence trying
to park the disk's head, which is obviously failing when the laptop disk(s)
is/are SSD(s), and there is no mechanical part (head to unload).
The easiest way to recreate the warning is to switch into a non-
graphical TTY (e.g. CTRL+ALT+F1) and just shake the laptop a little.
Even without logging in/starting a session in the tty console, the
warning will be shown on screen.
This is not really a big problem other than logs filling up with
warnings, and it's fixed by disabling/uninstalling hdapsd ( sudo apt-get
remove --purge hdapsd ). Hence, I'm not sure whether it should really be
reported as a bug.
However, upgrading Ubuntu to a new release actually re-installs hdapsd
automatically (re-invoking the logged warning messages), and I believe
that in an ideal world, the system would detect automatically that the
disk(s) is (are) SSD(s), hence only activating hdapsd in the case that
disk(s) is(are) really mechanical and in need of any head unload.
