Of course, you're meant to key it in backwards.

I think Alan mentioned it once or twice on this list.

With access to the kernel sources, you doesn’t have to remember what
the others do, see
‘/usr/src/linux/Documentation/admin-guide/sysrq.rst’.


This file doesn't exist on my system (not even the directory
"admin-guide").

I can find it under:

/usr/src/linux/Documentation/sysrq.txt
That’s interesting, I doesn’t expect that. Maybe we are using different 
kernel sources. Mine is ‘sys-kernel/gentoo-sources-4.10.12::gentoo’ but 
wait, I’ve found it also under ‘Documentation/sysrq.txt’ with version 
4.9.16 and it’s slightly a little bit different (in form not in content 
as far as I can see).


But in my case I even had no access to any file, because no command
was working anymore. So I think it is better to have these information
on a good old sheet of paper. ;-)
Ha, yes of course, a paper backup beats them all (under typical 
circumstances). ;-)

I have it on a small post-it-note stuck on the side of my monitor.  I'm
not sure, may have been Neil or Alan, that posted it this way.

Reboot Even If System Utterly Broken. 

That sort of stuck with me.  Still, I look at the sticky note to be
sure.  I found it on linuxhowtos.org which ironically, was translated
from a site in your language I think.  lol 

Anyway, it's handy to have around, just in case, and a little safety is
needed when it seems the Sun just went dark.  I wish I had that when I
did the hal thing.  Let's not go to far into that tho.

Most of the keys are documented here:

And even more in the kernel directory at Documentation/sysrq.txt.

R resets the keyboard. E sends a SIGTERM to all processes except PID1,
which is why you need to restart services after pressing it. I sends a
SIGKILL similarly. As you say S syncs ass filesystems, U unmounts
filesystems and remounts them readonly and B reboots.

Once you have got to E, you need to restart stuff. You may get away with
switching runlevels to bring up all your services, or you may decide that
once the system has got itself into a state that has you reaching for
SysRq, a reboot is in order.

It's rare that I have to go "all the way" with this but at least it does
flush things through the system and properly unmounts file systems
first.  That alone is some comfort.  I switched to ext4 which is
supposed to handle those things pretty well BUT why risk it if you can
unmount them properly, even if it is brute force. 

One thing about alt sysreq, once you get to a certain point, you have to
go "all the way" with it.  I've found that just the R and E generally
gets things back to a point it is accessible and I don't have to go
through it all.  I think once you get to the I or S, it's all or nothing
at that point.  Even after the E, you may have to start/restart some
init processes.  FYI, I'm pretty sure the S is what syncs the file
systems and the U unmounts everything.  Of course, the B reboots.  I
can't recall what the others do exactly.

I wonder if some guru that is familiar with this could shine some light
and share some wisdom.

Hi Dale,

thanks for this hint. Although I know about this "magic stuff", I don't
even have it enabled in my kernel. At the moment I'm happy that my 
system is working again so that I can do some other urgent tasks. But 
I will look closely at these function within the next time. Even when 
it is not possible to "repair" the system in the case of a crash, it is 
helpful to be able to write the cache to disk and reboot the system.

I wonder if this is related.  When I did my switch, I hit a point where
I had to start the alt sysreq key sequence.  I only had to do the R and
E part to get my console back tho.  At the time, I thought it may just
be some weird occurrence but now I wonder if it was related to some
update.  Once I got my console and login screen, I was able to login and
carry on, after getting all the services back running that got killed
off.  I got the login screen back after hitting the E part. 

I wonder, will others run into this sort of problem?  If so, what is the
best way to get back to normal?  For you, rebooting helped.  For me,
just starting the alt sysreq did the trick.  It makes one wonder.

Hi,
"Invalid Machine command" (forgot the exact error message) usually happened to 
me when I passed the wrong -march to GCC (e.g. -march=haswell on sandybridge 
cpus)

Can't execute it. "Invalid command".

There is one terminal (gnome-terminal) still open. This is the one
that I used to recompile everything. I'm logged in there as root.
But I cannot open another terminal. I don't even see what I'm typing
(no echo). I can only see the output.

AFAIK I don't have any binaries installed on my system.

Re: [gentoo-user] System borked after emerge -e world (SOLVED)

[wabe]

I tried to reboot the system. But even this did not work. So I 
toggled the power. The system booted without problems and it 
seems that everything works well again.

I wonder what caused the trouble. The last package that was
compiled successfully was media-plugins/frei0r-plugins-1.5.0.
The next package, which failed, was media-libs/libmypaint-1.3.0.
After that, the system was broken.

Now I resume the emerge process. 15 Packages are left. Right now
media-libs/libmypaint-1.3.0 was successful compiled. Waiting
for the rest.

Thanks for all answers.

Can't execute it. "Invalid command".

There is one terminal (gnome-terminal) still open. This is the one
that I used to recompile everything. I'm logged in there as root.
But I cannot open another terminal. I don't even see what I'm typing
(no echo). I can only see the output.

AFAIK I don't have any binaries installed on my system.

I don't know how to repair it because I don't know what exactly is 
broken. At the moment I can at least ask the M/L. I don't wanna lose
also this possibility.

I will wait for some time. Maybe someone else can give me a hint. If
not, I will reboot the system.

Did you run the revdep-rebuild command?
Keep running that until it completes succesfully.

Do NOT use binaries to speed things up. That didn't work for me.

Try rebooting, worst thing you'll have to do if it doesn't want to reboot
is boot a rescue image and mount it to repair it
