Crash in tme -- mm58167.c

I'm installing NetBSD 9 in TME and encountered a problem ... looks like =
NetBSD issues a read to the mm58167 GO register, which causes an abort =
in _tme_mm58167_bus_cycle().  I don't see off hand where the kernel =
actually issues this read (it does issue a write to GO in =
mm58167_settime_ymdhms()).  Anyway, I worked around this for now by =
making TME return a 0 for this register read and everything seems fine.  =
But I'm curious if this is new, and wondering if anyone's actually =
running NetBSD/sun2 in TME at the moment?

Thx.
