Overflow. Bang. garbage != BAD_APICID :) Still looks like we have a problem (see attached boot log). Maybe we should change that for loop to: for (bit = 0; kicked < num_processors && bit < BITS_PER_LONG; bit++) So we only loop for the actual number processors found in mpparse.c? This seems to work for me. -Andrew Theurer --Boundary-00=_/KNR/qLyTmC/5W9 Content-Type: text/plain; charset="utf-8"; name="260test3bk8patch1" Content-Transfer-Encoding: quoted-printable Content-Disposition: attachment; filename="260test3bk8patch1" GRUB version 0.93 (631K lower / 3668699K upper memory) +-------------------------------------------------------------------------+= ||||||||||||||||||||||||+--------------------------------------------------= =2D----------------------+ Use the ^ and v keys to select which entry is highlighted.
