This patch was applied to 4.12-rc3 as commit ID:
23220356d5ebc05ead9a8d697abb0c0a906fc81
Please apply this to 4.4 and newer kernels.
---------------------------------------------------------------------
The code in block/partitions/msdos.c recognizes FreeBSD, OpenBSD
and NetBSD partitions and does a reasonable job picking out OpenBSD
and NetBSD UFS subpartitions.
But for FreeBSD the subpartitions are always "bad".
Kernel: <bsd:bad subpartition - ignored
Though all 3 of these BSD systems use UFS as a file system, only
FreeBSD uses relative start addresses in the subpartition
declarations.
The following patch fixes this for FreeBSD partitions and leaves
the code for OpenBSD and NetBSD intact:
