dmesg output

I noticed that my X60s freezes with linux-libre kernel (Parabola) > 4.0.7.  Up to 4.0.7, everything was fine.

From 4.1.1, I noticed the following:
- during boot process, I have this: "Failed to find cpu0 device mode"
- then after an hour or so, the laptop completely freezes.  I am left with a snapshot of my desktop, and the only thing I can do is press and hold the power button.

This is still present in 4.1.2.

I am not sure that this malfunctioning is related to the graphics.

Please find attached kernel logs at boot (dmesg output).

I enabled drm.debug=0x06 in GRUB.

Also find attached the system logs at the moment my laptop last froze.

Also using X60s. Using kernel 4.0.8 and 4.1.2 provided by Fedora.
I found "Failed to find cpu0 device mode" message as well. However the freezing state does not appear.
So I guess it may be due to linux-libre kernel.
Comment 7 Robert Alessi 2015-08-02 07:39:40 UTC
I think that the "Failed to find cpu0 device mode" message is unrelated to this particular issue.  However, I mentioned it here because kernels older than 4.1 (namely 4.0.7) did not display it.

Having said that, I am now running 4.1.3 for almost a week, and my X60s does not freezes any longer.

"does not freeze". Sorry.
