Old ld_elf.so and 1.6P == dead dynamic binaries? (worked with 1.6O)

Folks:
	I'm trying to get my sgimips hardware up-to-date and came across
	this earlier this evening:

	I was running a 1.6O kernel and an older ld_elf.so (though I can't
	say of what exact date as I blew it away in order to get the box
	up and running and didn't note the date on it).  

	I rebuilt a 1.6P kernel as of ~ 1:50 EST, 3/06/2003 to add UNIONFS
	so I could get my userland build going again (needed to union-mount
	some more space to complete the build ; after rebooting with the
	new kernel, all dynamic executables I ran would dump core.

	Extracting a base.tgz I had cross-built on 2/28 from my i386 fixed
	things up to run again, but it was strange that things that had no
	issue on 1.6O completely fell over with 1.6P.  Any clues?  I do have
	one or two more sgimips boxes to upgrade, so I'll try and keep my
	eyes better peeled next time (and/or take notes) to see if this is
	just some glitch I hit or a more serious incompatibility.

	The kernels:
/netbsd
	NetBSD 1.6P (BABYLON_SOUND_SYSTEM) #0: Thu Mar  6 02:57:56 EST 2003

/netbsd.old
	NetBSD 1.6O (BABYLON_SOUND_SYSTEM) #0: Tue Feb 25 23:24:39 EST 2003

Any ideas appreciated,
--rafal

1.6 userland, 1.6N kernel, same result (sgimips here too). Didn't have
time to investigate, replacing userland with some releng snapshot solved
the issue.

Challenge S netbootproblem, SCSI?

Hello Everyone,

Well, I'm new to this list, new to SGI-hardware and new to 
netbsd-sgimips(but I run netbsd-sparc for a while now...) . I've gotten 
myself a Challenge S R5000SC180 and I'm trying to netboot it and install 
netbsd on it.

I got everything sorted out as far as I could find online and in the 
archives, but I haven't found an answer to this problem:

Whenever I try to boot from netbsd-INDY_INSTALL (I also tried 
netbsd-GENERIC_INDY, same problem)

                          Running

                            Starting up the

Yes, I guess it was pulled in working order from a serverroom. It boots 
IRIX as long as i don't put netBSD over it. I can't do anything with the 
IRIX-install as i don't have the rootpass... But anyway, I guess it's 
correctly terminated and such...

I also read this on this mailinglist:

http://mail-index.netbsd.org/port-sgimips/2001/11/14/0004.html

..seems there's no solution since? Maybe any one a clue for a working 
(older) kernel for the Challenge S? I don't mind the mezz-board and my 
phobos G100 card won't work(for now)

I believe the problem described above is related to a problem with the
SCSI Bus and Crontroller not being reset correctly by NetBSD during
startup.  This was resolved several days later in rev 1.3 of wdsc.c

There may be a problem with the DMA or Interrupt handling caused by
multiple HPC3's in you challenge S.
Target 1 was found, which is a healthy sign, but I suspect that it isn't
starting the sync negotiation correctly, which makes me suspect
interrupts are not being delivered correcly.

Will have a look over the sources to see if I can spot any problems.

In the meantime, could you send the output of a SCSI bus probe

nb: indy, for some reason, uses 0 as the initiator target, so setting a
drive to id 0 (as would be common practice in other systems) freaks the
system out. prom hinv will report this as disk on all targets.

i meant to get back to the list on this one:

the 33c95 on challenge mezz cards (used in the big iron as well as the S)
is undocumented, difficult to program, and requires microcode. it is
surrounded by enough weird glue logic that implementing a driver from
scratch would be "nearly impossible". sigh. no wide scsi for me.

Well, here you go, this comes by when I boot it(this one is from 
netbsd-INDY_INSTALL):

Are you trying to boot 1.6, or something more recent?  I'm not sure 1.6 was
ever tested on a R5kSC, but I think the workarounds for lack of secondary
there may have worked well enough... If you're running -current, I'm quite
sure it won't work as in CVS right now both because people have reported
issues with R5kSC Indys and because I still have a bunch of R5k cache code
which I haven't checked in (I should make time to get that checked in RSN).
