At least I can't boot them either.
Can't help you with any netboot images, though I assume the existing
ones in the archives (, images are in
actually work if they are loaded from GRUB and not from the OBP.
If there is no more recent version, I'll try to build something myself -
are there any pointers on how to go about this? Minimal OS or the
netinstaller in an .img would be preferred.
I described a possible setup to netboot with GRUB on . My used
version of GRUB is old (`sparc64-ieee1275-2.02+dfsg1-18`) but works.
This setup works similarly to identically for most of my machinery
(ia64, amd64, powerpc, ppc64, sparc64) and for me GRUB is able to load
"large" images (> 100 MiB, tested during my investigation on ) over
network w/o an issue. With a working sparc64 Debian installation it's
even easier to setup. You can host everything needed (I recommend:
dnsmasq (only for DNS), tftpd-hpa, isc-dhcp-server and possibly rarpd)
on a Raspberry Pi for example. I assume you're already familiar with
these services but just ask if you need some help in configuration.
I think that would help in quick testing, as I have multiple other
systems with Cheetah (UltraSPARC III, III CU and IIIi) I'd like to try
provoking the panics on.
Also, some older (UltraSPARC IIi and IIe+) systems are waiting for
recent Debian :-)
For testing multiple systems for anomalies I'd recommend to netboot with
a Debian root FS provided by NFS which saves you the time to install
Debian on every machine. There were two posts on the debian-sparc list
recently () by Anatoly that mentioned the `stress-ng` tool, which
might be helpful in provoking panics and possibly identifying the source
of a panic.
