I'll try building a smaller kernel from -current and mail it

Your web.de's mail server doesn't seem to like mine, so apparently
that never went through.


Sorry, I don't have an own mail server. :-/

 I've uploaded the kernel to Google Drive:

Thank you very much. I now tried this kernel, but the behavior sadly didn't change with it: 

```

printenv

netaddr=172.16.2.103
dbaud=9600
rbaud=9600
bootfile=bootp():/AC100267
bootmode=c
console=d
diskless=1
volume=10
path=bootp()
cpufreq=33

boot

Setting $netaddr to 172.16.2.103 (from server )
Obtaining /AC100267 from server
2410832+0+79424 entry: 0x80002000
```

No further output from here on.
How did you manage to get it compiled? Because I now also tried to get a kernel compiled myself: I tried with both NetBSD 6.1.5 and 7.1 (and respective `srcsys.tgz`) on an O2 - the fastest SGI machine I have that is supported by NetBSD - but I never succeed. It always fails early on with the following error: 

```

I followed [1] but I can't get it to work.
The other object files in this directory are ELF files, but this specific file is considered "data" by `file`: 

```
o2# pwd
/usr/src/sys/arch/sgimips/compile/GENERIC32_IP12_NEW/lib/compat
o2# file kern_exit_43.o
kern_exit_43.o: ELF 32-bit MSB relocatable, MIPS, MIPS-I version 1 (SYSV), not stripped 
[...]

kern_resource_43.o: ELF 32-bit MSB relocatable, MIPS, MIPS-I version 1 (SYSV), not stripped 
[...]
o2# file tty_43.o
tty_43.o: data
```
Even when deactivating all "compat" options I still get this error. Say can you build an Indigo R3k (IP12) kernel with the attached config file? It's stripped down to the assumed minimum, as the machine runs diskless I deactivated support for all on-disk file systems and devices I didn't see in the dmesg of your 1.6T kernel. Maybe the 2.5 MB is still too big, although the header of the config says it should be sufficient to be smaller than 3.5 MB. 

Cheers,
Frank
