Hi Andrew,
Thank you for your email. For me the problem is always there, no matter
how many times I soft or hard reset.
The installation notes recommend to upgrade OpenBoot to at least 4.28.0,
but mine is already 4.38.13. On the Oracle website, I can see there is
a firmware update available (8.9.11, mine is 8.9.10), but I do not have
their supported purchased, nor will I have.
I tried installing Debian a few times, and the installer boots, but then
fails at installing some package. The installer crashed once at
booting, which is unusual.
Maybe my hardware is faulty. I thought the buy was great, but I think
I'll just return it. The hardware is awesome, so now my x86 server just
looks cheap.
I'm disappointed by the idle power consumption: 250 W (as in the docs).
I guess all T-series Sparc systems are that power consuming.
Regards,
Irek

Hi Irek
I remember having this on pre-T-series Sparc 64 machines.
The underlying cause was incorrect alignment of data - eg 64 bit word is
stored as two 32 bit words, but misaligned on 32-bit boundary.
From my very hazy recollection of 15 years ago, the problem was in the
OpenBoot(?) or Forth code, and was data dependent. Possibly
data in the SC.
Typically, recovery required a power cycle, or possibly, rebooting
without a power cycle. Possibly several times.
I fix would be great as it would appear this problem can affect all
Sparc64 systems if the wind blows the wrong way. .
I am sure that there are people that understand this better than me, but
unfortunately, not very many.
regards
Andrew

Hi,
I'm trying to install OpenBSD 7.5 on SUN Oracle Sparc T4-1 that is
known
or expected to work.
I ask OpenBoot to boot from a CD:
ok boot cdrom
OpenBoot tells me:
The file just loaded does not appear to be executable.
Then asked to net boot with DHCP:
ok boot net:dhcp bsd.rd
My tftpd serves bsd.rd, and then OpenBoot tells me:
ERROR: Last Trap: Fast Data Access MMU Miss
I would appreciate it if someone could help me out.
Thanks & best,
Irek
