OpenBSD 6.0 (GENERIC) #1094: Tue Jul 26 16:40:58 MDT 2016

Machine: sparc64
>Description:
I'm trying to netboot a Sun Enterprise 250 with console input and output
redirected to the RSC (using `ofwboot.net` from OpenBSD 5.9). I.e. OBP
environment variables configured like that:
```
{0} ok printenv
Variable Name Value Default Value
[...]
output-device rsc screen
input-device rsc keyboard
[...]
```
...or using the defaults, which falls back to `ttyc` (`rsc` is an alias
to `ttyc`) if no keyboard or screen is attached. The machine crashes
before the boot process is finished.
This is not a show stopper as I can still use it without a problem when
using `ttya` as console port. But it would be great to be able to use
the E250 machines via RSC, because then only one cable is needed for
"full" remote control.
The problem seems to be specific to the E250 and its RSC console but not
to its UltraSPARC II CPUs, as the other machines I tested (Sun Ultra 10,
80, Enterprise 4500) didn't show any problems and as already mentioned
it works for the E250 if `ttya` is used as console port. It also works
for a Sun Fire V445 when using the console via its SC.
BTW I'm using a baud rate of 9600 for both `ttya` and `rsc`.
Here are the boot messages including the crash, the trace output, etc.
both for 5.9 and 6.0-current (builddate 1469576034) from the E250. Using
the MP kernels makes no difference. Further below some results from
testing earlier versions of OpenBSD with this machine and a possible
similar issue that seems to be solved in the sab driver of NetBSD 5.1 (I
didn't test the machine with NetBSD >= 5.1 though). If you need
additional info, please let me know.
OpenBSD 5.9

Trying to find an OpenBSD version where this works, I netbooted all
versions from 5.8 down to 4.1, but couldn't find a single version where
the RSC console works without problems. From 5.8 down to 4.3 all
versions stop output after the following messages:
```
[...]

swap on 192.168.0.9:/srv/nfs/e250-2/swap
```
...4.2 stops earlier after the `sabtty2` (the port used by the RSC) is
detected:

The same happens for 4.1, so I stopped testing at this version, assuming
that this never worked correctly for the E250 when redirecting the
console to the RSC.
With NetBSD it looks like there could have been a similar problem
(although I couldn't find a related problem report). The NetBSD 5.1
release message [1] includes this:
```
[...]
sab(4): Allow the RSC to be the console on an E250, by checking for
RSC-specific properties, and by not changing the port baud rate.
[...]
```
...and the man page of its sab driver [2] includes a note specific to
the E250:
```
[...]
NOTES
The speed cannot be changed on the ports connected the Remote System
Control (RSC) on a Sun Enterprise[tm] 250 Server (ttyh2 and ttyh3).
These ports are fixed at 115200 baud.
[...]
```
The relevant commits/revisions of the sab driver seem to be 1.43 and
1.44 [3].

>How-To-Repeat:
(Net)boot the OpenBSD 5.9 (build #914) or 6.0-current (build #1094)
kernel on a Sun E250 system with console output redirected to the RSC.
>Fix:
Unknown/Workaround: Use `ttya` for the `input-device` and
`output-device` environment variables in OBP and the boot process wents
through without a problem both for 5.9 and 6.0-current. Sorry, output is
from MP versions of the kernel this time, assuming that if the MP
kernels work, the uniprocessor kernels will also.
