any configuration could not boot, so there is no uname.

Using a GENERIC kernel, zstty @ zsc freezes while booting.
On the other hand, a GENERIC kernel with LOCKDEBUG,
zstty @ zsc passes successfully.

 zstty(4) works fine on cobalt and news68k without LOCKDEBUG,
 so maybe it's x68k specific.

 I wonder if zscn_cs in x68k/dev/zs.c:zs_putc() should be updated
 once after the device is attached during autoconf(9).

 IPL_SERIAL (which is defined as IPL_HIGH) is not initialized?

 (BTW, which ipl does zs use? 4 or 5?)
