I have a 'root on RAID1' setup NetBSD-8 box upgraded to NetBSD-9 which no longer auto boots.
There are six disks in the machine, but the relevant dmesg entries are: wd0: 5589 GB, 11628021 cyl, 16 head, 63 sec, 512 bytes/sect x 11721045168 sectors dk0 at wd0: "raid0part0", 134217728 blocks at 2048, type: raidframe wd2: 1863 GB, 3876021 cyl, 16 head, 63 sec, 512 bytes/sect x 3907029168 sectors raid0: Components: /dev/wd2a /dev/dk0 So, this is a RAID1 with one partition on a gpt partition and another on a disklabel (for historical incrementally upgrading reasons). In both cases the partition is 1M from the start of the disk. # disklabel wd2| ag ' a:' a: 134217728 2048 RAID # (Cyl. 2*- 133154*) # gpt show -i 1 wd0 Details for index 1: Start: 2048 (1M) Size: 134217728 (64G) Type: raid (49f48daa-b10e-11dc-b99b-0019d1879648) GUID: 1680cacb-62e6-4f81-a31a-7211bb8e0a08 Label: raid0part0 Attributes: biosboot Boots a NetBSD-9 kernel fine from NetBSD-8 boot blocks. Upgrading the bootblocks to NetBSD-9 gives.

A workaround in this case might be to fallback to traditional hdX: booting if the bootblocks are unable to locate the named wedge - the "NAME=raid0part0 not found" error David
