Description Alexander Schreiber 2018-11-25 22:09:22 UTC 
I tried to netboot the FreeBSD 11.2 installer (from FreeBSD-11.2-RELEASE-sparc64-bootonly.iso)
on my Sun V100 by using boot/loader binary as the netboot loader over tftp and
it failed.

--------- snip -------
ok boot net
Boot device: /pci@1f,0/ethernet@c  File and args: 
47e00 Consoles: Open Firmware console  
Fast Data Access MMU Miss
ok 
--------- snip -------

This is reliably reproducible.

However, using the boot/loader binary from the FreeBSD-10.3-RELEASE-sparc64-disc1.iso reliably loads and boots both the FreeBSD 10.3 RELEASE and the
FreeBSD 11.2 RELEASE installer kernels.

NetBSD 8.0 boots fine (and the machine ran FreeBSD 10.2 for months with
ZFS), so I assume it is the 11.2 loader and not my machine.

Update: Finally got around to replacing the CDROM drive in that machine,
tried to boot from FreeBSD 11.2 installer DVD. Except here the loader dies
as well. It starts reading from the drive and then dies.

what does 12.0 release do?
Comment 3 Alexander Schreiber 2019-01-09 20:57:39 UTC 
Ok, wiped the root disk, installed FreeBSD 12 RELEASE to the machine
from DVDROM. Verified that the loader now successfully boots from local disk.
Cloned that setup for netbooting and the loader now also successfully 
netboots.

So, moving to FreeBSD 12 RELEASE for sparc64 fixes it.
