Hi Matthew,
   GIT commit  660e34cebf0a11d54f2d5dd8838607452355f321 x86: reorder
   reboot method preferences causes my Acer Aspire One to hang on
   shutdown/reboot. 

   I'm running the original Aspire One A110, BIOS version 3310.

   Booting with reboot=k or reboot=b both work; so it looks like an
   ACPI firmware bug.

   I printed out the FADT bits that were relevant---it claims revision 4
   in the header, and the ACPI_FADT_RESET_REGISTER bit is set in the
   flags.  The values of the reset register's address and width look
   reasonable (address 3321 in IO space, width 8 offset 0)

   I'm not sure of the best fix:  one could I suppose add the Aspire
   One to the list of machines that need BIOS reboot.  Is there a
   cleaner fix?

Peter C
