Had some time to also try other machines/configurations not yet tested with OpenBSD/sgi 7.0 to 7.3, namely:

• R4600 Indy
  
• dual-node R10000 Origin200
  

All of them worked (Indy: tested both booting and operation with 7z and openssl; Origin200: Only tested booting with the mentioned versions). On the Origin200 the 7.2 kernel did trap one time when booting, but two subsequent boots went through w/o an issue.

The R4600 Indy seems to be unaffected by the issue I mentioned in https://forums.irixnet.org/thread-3788-p...l#pid28314 but later confirmed as being present in 6.9 already, i.e. it can run 7z w/o getting the kernel to panic. The only thing making it unresponsive is swapping over NFS. 

I uploaded the boot logs to dmesgd.nycbug.org and they are also linked from the respective release pages on GitHub.

The astute reader will not only notice that OpenBSD/sgi can access the hardware of the second node but also the information hidden in this portion:

Code:

origin200-2# sysctl hw
hw.machine=sgi
hw.model=IP27
hw.ncpu=2
hw.byteorder=4321
hw.pagesize=16384
hw.disknames=
hw.diskcount=0
hw.cpuspeed=180
hw.vendor=SGI
hw.product=Origin 200
hw.physmem=1207959552
hw.usermem=1207926784
hw.ncpufound=4
hw.allowpowerdown=1
hw.ncpuonline=2
hw.power=1

So it found four CPUs but only uses the two of the master node.    Looking around in the sgi code I came across these two parts here in sys/arch/sgi/sgi/ip27_machdep.c:

Code:

int
ip27_kl_launch_cpu(klinfo_t *comp, void *arg)
{
[...]
    /* XXX Skip CPUs on other nodes. */
    if (comp->nasid != ci->ci_nasid)
        return 0;
[...]
}

Code:

int
ip27_kl_attach_cpu(klinfo_t *comp, void *arg)
{
[...]
    /* XXX Skip CPUs on other nodes. */
    if (comp->nasid != ci->ci_nasid)
        return 0;
[...]
}

Unfortunately I wasn't equipped with the required hardware to produce a kernel when I tested the machine yesterday. I wonder what will happen with these two parts disabled - Here be dragons! My Octane is already compiling an IP27.MP kernel modified in that regard as I write, can't wait to test it on that Origin200, maybe on the coming weekend, we'll see.
