Hello!

Could someone write the steps I need to follow (what to type in the command prompt) in order to download and install a realtime kernel in an Ubuntu system (version 16.02)? I am new in Linux and I have no idea how to do it, I only managed to download a low latency kernel but it shouldn´t be enough for my application.

Thank you very much in advance.

FYI, nvidia-dkms ought to work again

@blackhole: I've asked the -rt devs and they seem fairly convinced that the problem lies in the vbox modules doing something that works on vanilla but breaks on realtime. They said that it's hard to tell what is going on due to Arch's low loglevel. They suggested to add the following to the kernel flags, to see if there would be better console output: "debug ignore_loglevel printk.devkmsg=off"

The debug flag might be picked up by systemd though, thus the reason for "printk.devkmsg=off". They were unsure if systemd would spam the console anyways, but let's try it?

I have installed to MSI H81M-E33 + i7-4770 with 6 usb ports connected. I am sure it is a timing problem, however. I have booted with blacklisted vbodrv modules, after I have loaded manually and no crash.

@blackhole: What kind of hardware do you have?

Here the problem is that vbox modules are compiling just fine, but once loaded the boot process crash.
This is not occurring all times. Maybe it is a question of loading order, I don't know.
I think I will use a little script trick: I will blacklist them by default while loading the modules with Desktop environment autostart if the kernel is not realtime.

@blackhole: There is a discussion lower down about similar problems in the past, maybe helpful? Were the boot problems due to the vbox modules?

Realtime kernel is incompatible with virtuabox modules...
I have disabled all

blacklist vboxpci
blacklist vboxnetflt
blacklist vboxnetadp
blacklist vboxdrv

and now boot is fine!

I have a lot of errors and boot hangs
See screenshots http://www.tophifi.it/ftp/temp/boot/

Standard kernel 4.9.x is booting fine on the same machine
