Re: 1. dscheck(vn0): b_bcount 2 is not on a sector boundary

Hello Jonathan,

thank you very much for your reply. What I find strange is that these 
complaints only occur after installing mate or gnome. Without mate or 
gnome there are no complaints. Also, in a previous post I attached the 
boot messages from a verbose boot. They additionally spewed this out:

md1: invalid primary partition table: no magic.

I guess this has something to do with the fact that after installing 
DragonFly, I used OpenBSD to change a partition type on the same hard 
drive to A6 and Linux to change another partition type to 8e00. Maybe 
these manipulations by tools from other OSs have somehow changed the 
partition table so that DragonFly now complains?

Anyway, apart from these complaints the system works perfectly. Unless I 
get further clues, I am going to ignore the complaints.

Best regards,

Martin
