>Description:
	I have a dual hypersparc ss20 which is currently running 1.6M
	of Jan 26 vintage, both kernel and user-land.  It "mostly"
	works in MP mode, but that's not the problem I'm reporting
	here.

	Recently I've tried to upgrade the kernel to 1.6P of Feb 27
	vintage (initially trying with an uni-processor kernel to
	avoid any MP issues).  Booting the kernel single-user presents
	a problem starting the shell, though:

Enter pathname of shell or RETURN for sh: 
Mar  1 16:05:41 init: single user shell terminated, restarting
Enter pathname of shell or RETURN for sh: /bin/csh
Mar  1 16:06:23 init: single user shell terminated, restarting
Enter pathname of shell or RETURN for sh: 

	At this point, init is running, but the major difference
	between init and the Bourne shell (and csh) is that init is
	statically linked, while the two others are not.

/lib/libc.so.12: ELF 32-bit MSB shared object, SPARC, version 1 (SYSV), not stripped
grizzly: {11} 

	However, the new kernel *is* able to run the binaries from
	/rescue, all being "the same" statically linked program.

	Trying to run the normal shell (or apparently any dynamically
	linked program) results in an Abort trap and no core dump:

# export PATH=/rescue:$PATH
# mount
root_device on / type ffs (read-only, local)
# mount -u /
# /bin/sh
[1]   Abort trap              /bin/sh
# /bin/ls
[1]   Abort trap              /bin/ls

# /bin/ksh
[1]   Abort trap              /bin/ksh
#

>How-To-Repeat:
	Boot new kernel, watch it fail to run dynamically linked
	binaries.  Please note, user-land is unmodified between these
	two attempts ("of course").

	Sorry, don't know.
