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

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. Adrian -- .''`.

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).

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. Cheers, Gabriel

No login prompt after booting in LDOM on SPARC Enterprise T5120
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
