short update / hint: if for the very first time after the install the system does not boot, go to a running system and try to configure the 55 bsd kernel:
config -o bsd.fix -e bsd and remove the radeondrm module (find and disable are your friends, type help at the UKC prompt). Then boot with "boot hd0a:/bsd.fix". rgds, Volker > Von: Volker Nowarra <volker.nowa...@me.com> > Betreff: Aw: fail to boot snapshot 5.5 on MBPro8,2 - solved, X also working. > Datum: 10.
