Description

When trying to boot from intermediary Tails 2.10 installed using dd ocmmandline (from Linux though), the resulting Tails USB is recognized as bootable on a MBP 9,2, starts to boot but get stuck with a black screen and a top-left blinking cursor.

I can try to see if I can reproduce that bug using dd from OSX first, and using another USB as well, and Tails3.0-beta1.
It could also be tested on different models of MBP as it might be hardware specific.

I tested the following, always using intermediary Tails USB installed using dd on Linux:

  • 1.8.1
    - on MBP 9,2: doesn't boot
    - on MBP 9,2 failsafe mode: doesn't boot
    - on MBP 9,2 adding 'edd=off' to boot commandline: boots
    - on another non Apple laptop: boots
  • 2.10
    - on MBP 9,2: doesn't boot
    - on MBP 9,2 failsafe mode: doesn't boot
    - on MBP 9,2 adding 'edd=off' to boot commandline: boots
    - on another non Apple laptop: boots
  • 3.0-beta1
    - on MBP 9,2: doesn't boot
    - on MBP 9,2 failsafe mode: doesn't boot
    - on MBP 9,2 adding 'edd=off' to boot commandline: boots
    - on another non Apple laptop: boots

I don't remember receiving much user reports having this issue, so it's probably hardware specific. I can't do much test on different MBP models.
Should we document this in the known issues page?

A test with Tails 2.10 installed the same way booted fine on another MBP 9,2 (i5 version while original post was with a i7 one).

They don't have the same "BIOS" version though, the one which boots has an older one.

I'm wondering if it's worth trying to go deeper in debugging this (update BIOS to latest version to see how it works or not) or simply have a note on the known issues or installation assistant page about that.

I see very little we can do about it on our side (we're not kernel developers), so now that a workaround was documented, I'm going to close this ticket. Feel free to follow-up about this upstream (Debian or Linux) after having reproduced on non-Tails with a very recent kernel. Sorry I can't be more helpful!
