[Driver extension jun 1.02b/DSM6.1.x for 3615xs / 3617xs / 916+]

Hi all. Faced with strange bug, maybe someone could help.

Got an ASUS P9A-I/C2750/SAS/4L motherboard with two Marvell 88SE9485 controllers onboard.

Made a bootable usb flash with 3617xs image, put there extra.lzma v4.7, installed DSM successfully.

All works fine, except sas-controllers:

For some reason driver doesn't recognize controller.

Checked device id's in kernel sources at https://sourceforge.net/projects/dsgpl/files/Synology NAS GPL Source/15047branch/broadwell-source/ - mvsas driver have these ids in mv_init.c

There is nothing in dmesg regarding mvsas.

Also all work fine on Ubuntu 17.10

Have no idea what to check next.

Please help
