NetBSD/evbarm 7.1.1 (armv7.img) not able to load device mapper module

[Matthias Petermann <matthias%petermann-it.de@localhost>]

Hello,

recently I am trying to build a small storage appliance based on a 
BananaPI (BPI). For that, I need the LVM / device mapper module.

Regardless of whether I set the dm module in modules.conf, or try to 
load directly in single user mode via modload - the result is the 
following error in the kernel log:

WARNING: module error: recursive load failed for `dm' (`dk_subr' 
required), error 8

[truncated]

On the IRC I got the hint that the lack of symbol for strcpy et al 
suggests that libkern is absent or corrupt.

Unfortunately, I still lack a little insight at the moment, how all this 
is connected. That's why I'd like to ask what steps I could take to 
narrow down the problem.

Does anyone have an idea or recommendation? I would be very grateful for 
that.

Best regards,
Matthias
