That's a R4600 V2.0.  The kernel sources/binaries on Linus don't handle
the silicon bugs of this beast correctly.  I fixed the problem this
morning testing them on a SNI RM200.  For a proof of the test I compiled
X a couple of times; the box now looks stable even under high load.  Will
commit the bug fixes shortly.

The Indy actually seems to show the problem somewhere during or after the
initialisation of the serial driver but by my experience this CPU bug
causes all sorts of symptoms indicating everything else ...

Ralf:
	Has anyone attempted to build the binutils fixed RPM with the old
buggy binutils. Im trying this right now and Im getting

1.	build the srpm

2.	build the srpm static

3.	link the stuff again with the static srpm but dynamic

All the binaries crash at the same reference (000000d0 from a fixed address
so I guess its a dynamic linker error).

Im now off to rebuild it from scratch with the static new linker to see what
occurs

I just checked the binutils on my (Intel ...) laptop.  Libbfd contains
DT_NEEDED entries for libc.so.6.  This means that libbfd was linked
against libc which will make binutils 2.7 produce bad executables.

Suggested bootstrap procedure:

  - restore your old binutils 2.7 binaries
  - manually rebuild binutils 2.8.1 + patch.  When configuring binutils
    2.8.1 do not use the --enable-shared option, it will make binutils
    2.7 generate bad libraries.
  - install the binutils just built
  - You should now be able to rebuild the rpm without problems

Done that. I get a static and apparently workable binutils if I also turn
gcc optimisation off (otherwise gcc dumps)

gcc still dumps, if I fix that I get back to the original problem. This
is the 2.8.1 off sgi.com and has a "mips patch" listed in the spec file.

Im guessing the gcc one is a link bug that damaged gcc just slightly - zsh
also dumps gcc.

In that case you are probably the victim of an older libc.  I'll rebuild
libc for my sources for big endian machines asap.

libc and glibc binary RPMs would be appreciated. How about gcc and
binutils for big endian as well?

Okay.  I'm getting somewhere now.  I know I'm behind most people, but my
system now boots with a local root.

Does anyone have an editor?  It's a bit of a pain to have to FTP things
over to my i386 box, change, and re-FTP.

I'm attempting to build some more RPMs, but I'm hitting some snags with my
setup. Details as they become available...

I'll upload them rsn.  Just give some more days.  My next upload will
probably again be 100mb or so, that takes a while to compile.  Also I
don't have a network connection at home that is suitable for pumping
gigs through the world, so that will suck additional time.

I'm pretty shure that I put a tarball with Elvis and several rpms with
other editors on Linus.

Cool!  Now that things are working a bit better on my box, I'm a little
more eager to get things running smoothly.

Uh, could you let me know where?  I couldn't find either. The only RPMs
are ed(no, please, don't make me)  and the broken version of joe.

I've had SRPMs of RedHat 5.0 (Hurricane) for a couple of days, so when I
get my build system running well, it'll churn out the upgraded RPMs.
Having compiled a few things this evening, I can tell you it'll take a
long time.  The 4600 isn't as fast as I'd thought.

If you have the tree from /devel you probably dont quite have final 5.0
We'll soon find out. My 5.0 CD should appear pretty soon and I'll mount
the SRMS directory of it somewhere for ftp.

I just started rebuilding libc.  Boy, I didn't know that the last published
version of libc was that buggy.  *grin innocent*

Also to be released: Eeekmacs 19.34 tty and X version.

I can't get rid of the feeling that performancewise something is very wrong 
with the Indy code.  My R4600 box feels faster than the R5000 Indy.

Seeing as how I actually have the CD in my hand of the SRPMs, I'm quite
sure I have the final ones.  They'll be in
ftp://ftp.engsoc.carleton.ca/pub/redhat-5.0 by the end of my day.

And vim, and apache, and bash...  very cool.  I didn't know there were all
thos packages there.

Does anyone have any objections if I put all those RPMs on
ftp.linux.sgi.com ?  It would save folks from having to look in two

Alright.  I'v put all the RPMs on ftp.linux.sgi.com. Where there were
overlaps in packages, I put the older version in the mips-linux/old
directory and I included the newer.
