As per svn and cvs: r199112 | kensmith | 2009-11-09 16:39:42 -0500 (Mon, 09 Nov 2009) | 11 line= s Changed paths: M /stable/8/sys/amd64/conf/GENERIC M /stable/8/sys/i386/conf/GENERIC M /stable/8/sys/ia64/conf/GENERIC M /stable/8/sys/powerpc/conf/GENERIC M /stable/8/sys/sparc64/conf/GENERIC Comment out the sbp(4) entry for GENERIC config files that contain it. There are known issues with this driver that are beyond what can be fixed for 8.0-RELEASE and the bugs can cause boot failure on some systems. It's not clear if it impacts all systems and there is interest in getting the problem fixed so for now just comment it out instead of remove it. Commit straight to stable/8, this is an 8.0-RELEASE issue. Head was left alone so work on it can continue there. Reviewed by: Primary misc. architecture maintainers (marcel, marius) Looks like sbp(4) is disabled on the 8.0 branch already. --Dave
