Just out of interest, the dumpdev must be a 'b' slice.. This is enforced in i386/machdep.c... dumpsys() ... if ((minor(dumpdev)&07) != 1) return; ... This (IMHO) is pretty bogus, especially when I was trying to use a specially reserved slice for a dump partition that wasn't going to get spammed at boot. I never could figure out why crashdumps were not going in.. I "discovered" this a few weeks ago and let off a scream of anguish at the hours/days of wasted time from several months ago. -Peter > Terry Lambert > terry@lambert.org >--- >Any opinions in this posting are my own and not those of my present >or previous employers.
