Hi,

i have the same problem and setting kern.geom.part.check_integrity=0 works. I
installed my system using sysinstall from 8.2-amd64-CD1.

Ciao,
Uwe

Your partition has start offset below the first LBA.
As temporary workaround you can set loader tunable
kern.geom.part.check_integrity=0 (recently added to CURRENT)

What tool did you use for partitioning?
