I see this tracing (from the lock-dependency validator?) for several -mm
versions. This is from a Silan ethernet card (CONFIG_SC92031).
00:0b.0 Ethernet controller: Hangzhou Silan Microelectronics Co., Ltd.
Unknown device 2031 (rev 01)
Other than the tracing, I'm not having any problems.

------------------------------------------------------
ip/3036 [HC0[0]:SC0[2]:HE1:SE0] is trying to acquire:
