Need an account on a Linux/Mips box

Need an account on a Linux/Mips box

[Emmanuel Dreyfus]

Hello everybody

I'm working on Linux compatibility on NetBSD/Mips. In order to implement
things such as signals, I need a user account on a big endian Linux/Mips
system.

I would use this account mainly for building and running tests programs,
in order to check that our Linux emulation is accurate.

Anyone can helop here?

We have an SGI Indy (R4600 100Mhz CPU, 96MB RAM, 6.5GB HD) running
Debian (Sid) which is available for developers who need access to a
MIPS computer.  Please email me if you want an account.

Does it run without any problems? What kernel (with what patches?) are you
running. I'm having troubles running our R4600-Indy:

- Perl is seg-faulting (especially when a perl-script is calling another)
- bind9 hangs after a few days
- occasionally the box just stalls and returns to the bootprom
- sometimes it just dies and we have to power-cycle it

I'm using kernel-image-2.4.5 from debian but we've had these problems
all through 2.4.x.

Would be nice to hear if anyone has managed to get 2.4.x running on
an R4600 without problems. R4000 and R5000 seems to be ok according to this
list...

Regards

Raoul

I'm seeing the same here. The gdb output of these segfaults is rather
weird too(gotta look that one up though). Never found time to look
deeper into this.

Hmm...I'm sure that very early 2.4.x kernels worked quiet well on R4600.
One way to hunt the problem down, would be to roll back to 2.4.0 and
spot the point in cvs where things break.
Could it be possible that things fail since glibc uses sysmips?

Apart from sshd (OpenSSH), which started dying from SIGFPE (floating
point exception, whatever that means :) a few days ago, it's working
OK.

We're running 2.4.5 from CVS (~ 2001-08-08) with the sysmips-patch,
self compiled with gcc 2.95.4.

(If you're interested, both the kernel and the patch can be found at
http://www.ping.uio.no/~toffer/linux-mips/.)

Hm.  It's not entirely unusual for dist-upgrades to segfault in
various pre- and post-installation scripts.  That doesn't happen very
often, though, and it seems to be the same packages every time
(e.g. zsh), so I'm not sure whether it is a Perl problem or not.  I'll
try to take a closer look at it next time it happens.

I installed bind9 on the development box now, to see if I can
reproduce it.

Apart from xdm, which oopses all our Indys, I have seen very few
crashes like this on the various Indys I use.  They are great X
terminals.  :)

Toolchain update problem - recompiling fixes this. I've put recompiled
debs at:

Thanks, they seem to work fine.

Concerning the other R4600 issues: Our R4600 Indy has 11 days of
uptime now, and Bind 9 is still running fine.  When I switched back to
ssh from ssh-nonfree just now, the calls to update-alternatives in the
prerm-file segfaulted repeatedly.  I'm trying to gather the patience
to debug it now.  :)

Installation instructions

[Petri Tapio Koistinen]

Hi!

I have seven Indys for Linux and NetBSD use. Is there somewhere
installation instruction from point zero. Is there CD-ROMs available where
Debian/mips can installed.

Thanks!

Petri

Quick and dirty hack that might work (I had quite a number of segfaults during
installation and this trick did work): change the /bin/sh between bash and
ash.
