Does it holds for any of these? Or do you require a combination of factors? I ask because I have two identical HP machines, one running 7.1p2/amd64, the other still at 7.1-PRERELEASE/amd64 and on both I get: # camcontrol tags da0 (pass1:ciss0:0:0:0): device openings: 254 So it looks like I'm not affected, although I have a ciss RAID. ??? bye & Thanks av.
