Kernel messages from netconsole
After login attempt the screen freezes completely and even the mouse doesn't move.
On login the screen freezes completely and I cant even ssh into the machine. The only option then is to press the reset button. Since the system freezes on login I could get the kernel messages only by using netconsole. It occurs every time.

I forgot to mention that my machine is an old machine with Nvidia 7050.
[ 5.710] (EE) [drm] KMS not enabled
[ 5.710] (EE) open /dev/dri/card0: No such file or directory
You need to look into that -- is /dev/dri/card0 really not there, or are the permissions just messed up (e.g. you're trying to run X as non-root and not in the right group). This means that nouveau isn't really being used by X.
Separately, we've recently disabled MSI on all nv4x IGP's -- it was just causing too much trouble for too little gain. Try booting with
I'm sorry, that Xorg log I attached before is the log which I got after booting with nomodeset as the kernel parameter, because that is the only way I can login. Otherwise the system completely freezes after login so there is no way for me to retrieve the Xorg log.

Xorg log after logging in
Strangely I could login once and before it hanged I collected the Xorg log.

This is the netconsole log when I could login and it didn't hang for a while.

I booted with the parameter nouveau.config=NvMSI=0
Now I am not even getting to the login screen. The screen freezes showing:

Any change if you boot with nouveau.config=PMPEG=0 ?
I tried it the first time and it hanged even before I could get to the login screen. But the second time I could login and it didn't freeze and it worked fine. I tried it again and it again hanged before login screen appeared.

It did hang with nouveau.config=PMPEG=0 but this time I could ssh and get the dmesg and Xorg log.

Xorg log after booting with nouveau.config=PMPEG=0
I am able to switch to a virtual terminal using Ctrl+Alt+F1. So (I think) KMS is working.
