Sun2/120 emulation on tme (installed from pkgsrc/emulators/tme)
Architecture: m68k (m68000)
Machine: sun2
>Description:
While RAMDISK and FORMEG kernels in 3.0 boot and work fine on tme,
INSTALL kernel (both in miniroot.fs and NetBSD-3.0/sun2/binary/kernel dir)
hangs during boot:

Note INSTALL kernel in 1.6 also worked.

>How-To-Repeat:
Boot sun2 INSTALL kernel on tme:

% (cd [somewhere]/pkgsrc/emulators/tme && make update)
 :
% mkdir tme-sun2; cd tme-sun2
% cp /usr/pkg/share/examples/tme/SUN2-MULTIBUS ./MY-SUN2
% ftp http://theory.lcs.mit.edu/~fredette/tme/sun2-multi-rev-R.bin
 :
% tme-sun-idprom 2/120 8:0:20:00:00:01 > my-sun2-idprom.bin
% cp /usr/pkg/share/examples/tme/sun-keyboards.txt .
% cp /usr/pkg/share/examples/tme/my-sun-macros.txt .
% mkdir my-tape
% (cd my-tape; ftp http://theory.lcs.mit.edu/~fredette/tme/sun2-tapeboot.bin)
 :
% (cd my-tape; ftp ftp://ftp.dti.ad.jp/pub/NetBSD/NetBSD-3.0/sun2/binary/kernel/netbsd-INSTALL.gz)
 :
% (cd my-tape; gunzip netbsd-INSTALL)
% (cd my-tape; ln -s sun2-tapeboot.bin 01; touch 02; touch 03; touch 04)
% (cd my-tape; ln -s netbsd-INSTALL 05)
% env LTDL_LIBRARY_PATH=/usr/pkg/lib tmesh MY-SUN2
 :
tmesh> command tape0 load my-tape/01 my-tape/02 my-tape/03 my-tape/04 my-tape/05
tmesh> command mainbus0 power up
 :
- type "b st()" on PROM monitor prompt (on tmesh window)


>Fix:
Removing "options MALLOC_NOINLINE" from sun2/conf/INSTALL config
seems to resolve this, but I'm not sure why.
(RAMDISK and FOURMEG don't have the option)
