It definitely says:

"[ 1951.095382] f02969dc: ttyS0 at I/O 0x0 (irq = 1, base_baud = 115200) is a 
SUN4V HCONS^M"

So just passing "console=ttyS0 keep_bootcon" has to work. If it
doesn't, there might be something incorrectly configured with the
hardware.

There isn't really anything else that needs to be done to get a serial
console.

Also, I've already tried changing /etc/default/console-setup and it
edits itself back to its former state.

I've attached a log with the console boot option (log) and another one
without (log2).



log
Description: Log with console boot option


log2
Description: Log without console boot option

No, that should not be necessary. I honesly have no idea why it's not
working. I just added "console=ttyS0,115200,8n1 keep_bootcon" and
it works.

Can you please provide the full log of boot messages from SILO to when
the system is finished booting during a normal boot where you cannot
get a login prompt? There must be something wrong in your
configuration.

Just adding "consoel=ttyS0" is normally always enough.

Can you check the contents of /sys/dev/char or /sys/class/tty?

Maybe the driver for the serial console is missing in the kernel and we
need to enable it.

I'll do it tomorrow. I'm too tired to continue and I just shut down the
server for the night (it takes really long to boot up).

There's a difference between the console name and serial device name; ttyHV
just means it's a SUN4V hypervisor console, but it will be given a ttyS[0-9]+
name (for example, the machine I am currently on also has a ttyHV0, but the
device node is /dev/ttyS0).

James

It may be named ttyHV0, but as much as I have tried it with that name,
it still doesn't work. However, I've been able to boot to shell
(bypassing init) and there is no /dev/ttyHV0 in the filesystem. I'll see
if I can try more stuff tomorrow.

Are you sure that ttyS0 is the name of your serial device?

Check the kernel messages. It might be named differently.

keeping the console stuff, I get output until here:
[12194.169207] Btrfs loaded, crc32c=crc32c-generic

if I only use keep_bootcon, i get until:
 Starting Update UTMP about System Runlevel Changes...
[  OK  ] Started Update UTMP about System Runlevel Changes.

But no login console in neither case.

Can you try adding "console=ttyS0,9600,8n1 keep_bootcon"?

No login prompt after booting in LDOM on SPARC Enterprise T5120

2017-07-19 Thread Gabriel Pérez-Cerezo 
Hi,

I'm running a SPARC Enterprise T5120 with OpenBSD in the primary Logical
Domain. I have installed Debian successfully in an LDOM, however, I
haven't set the recommended options for T5120 in /boot/silo.conf. I have
tried booting it with the workaround (Linux console=ttyS0), but it also
doesn't show anything (in fact, boot output ends earlier). Does anyone
know what options I should give to the kernel in order to boot into a
login screen?

Thank you in advance,

Gabriel
