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
