[Bug 1019496] Re: Ubuntu 12.04 hangs on reboot


I would love to answer you Christopher M. Penalver (penalvch), but I no
longer own the machine that had this issue. I owned the Acer Aspire
10.1" AO531h. It would shut down properly but not restart properly. I
bought the Compaq CQ57 229wm model, and it no longer had this issue.

So it is clearly linked to the hardware on the Aspire.

I mention again though that at that time, the Aspire worked beautifully
with virtually all other Linux distributions, it just didn't work with
Ubuntu 12.04.
