It appears there used to be a section about this issue on the "known issues" page, but it is gone. However, a user has reported facing this problem. May I ask why this has been removed?

It's good to document problems. It's better to fix them :)

For the record, the section that we removed was:

We removed it because it was very old (2013!) and related to an implementation of the memory wipe procedure that we're not using anymore, since 3.0 I think. Search for "Shutdown" in

So my bet is that this user faced a different issue that the one that used to be documented.

Were the symptoms the same for this user?

Do you have any more information?

#2 Updated by numbat 6 months ago

I've asked the user for more details on their hardware and attached a screenshot provided.

When the user attempts an emergency shutdown it may end up in a kernel panic, the user must then manually shutdown the hardware. The chances of this bug occurring is higher when the system is active, while doing things that are RAM intensive.

Hi numbat,

When the user attempts an emergency shutdown

Do you know (or could you ask) how exactly they're triggering shutdown? (We don't have a well defined terminology and this area, and different people mean different things with "emergency shutdown".)

Can the user reproduce this with 4.0? (on the screenshot I see a 4.19 kernel is running, so that's not Tails 4.0 :)
