Switching to AHCI on a SSD doesn't makes sense because one of the
feature of ahci is NCQ (Native Command Queuing) which optimize the way
the heads are moving on the hd plates. It (should) greatly increases the
performance of standard rotational drives but it has no bearing on SSDs.

Thanks for confirming Jean-Baptiste - the S12 has a Intel Atom N270
processor, a N10 chipset and a ICH7 IDE controller. So my test data is
moot on most system (unless e.g. the mini9 shows similar symptoms).

That really seems hardware specific.

The puzzle seems to be solved (at least for the s12). When I switch the
S12 from "AHCI" mode to "compat mode " (in the bios) I get 30s OOo
upgrade times and no keypressing needed anymore.
I wonder if the mini9 (who presumably has the same chipset) has also a
AHCI set in the bios as sata mode?

The data is pretty interessting, when comparing ext4 vs ext3 with the
dpkg from lucid-proposed its a difference of "3:11min" vs "00:39sec" for

seems to be disproportional on the atom based systems.

Thanks for your report.
I'm unable to reproduce the problem in a VM (no ssd) where the upgrade runs in
less than 1 hour, so this could be related to the hardware.
Could you please attach the output of dmesg just after the boot of your system
to this report.
Thanks.
