[42949377.980000] SCC: open port done! This is logged hundred of times. I installed the m68k-linux-gnu cross-gcc and binutils, so I can cross-compile a kernel myself. I just need to have the kernel config file you used to build 2.6.26, plus some hints :-). -- Patrice Mandin WWW: http://pmandin.atari.org/ Programmeur Linux, Atari Spécialité: Développement, jeux -- To UNSUBSCRIBE, email to debian-68k-requ...@lists.debian.org with a subject of "unsubscribe".
