Hello Friends:

Lately my laptop started freezing randomly, but regularly. Here is it's configuration:

- Fedora-25/64-bit
- Kernel: 4.11.3-202
- Nvidia 381.22-2 from the Negativo17 repository
- XFCE-4 desktop GUI (nothng fancy)
- Lenovo Y700 laptop
- GPU: Nvidia GTX 960M
- This is an Optimus-based laptop, with switchable graphics (between the integrated INTEL GPU and
  the NVIDIA GPU). But I have it configured to always use the NVIDIA GPU (I believe. It's
  sometimes hard to tell).

It is configured to have the NVIDIA GPU active at all times (I think; its been a while). That the following command works, I think means that the NVIDIA GPU is the active one.

user$ glxgears

Anyway, probably after some recent dnf upgrade, the laptop semi-regularly just freezes; and absolutely nothing is responsive when that happens: mouse & keystrokes, are all dead. I can still SSH into the box to reboot, but it is so hosed that when it reaches the init-0 phase, the screen stays blank, keystrokes still don't work, and it never completes the reboot (it just stays stuck near the shutdown stage). The only recourse, then, is to hard power-off by holding down the power button.

It was working perfectly, and for a long time. I made no changes other than issuing "user$ sudo dnf -y update", which I do regularly. That, of course, can do it. But my point is that I didn't introduce any other modifications ... just a simple, "Let's update the packages".

Any ideas what could be suddenly causing this? I saw similar issues online about this, but some date several months back.

Thank you! :)

@steveebey73742 Thanks for your setup info. I upgraded to that kernel (4.11.4-200.fc25.x86_64) yesterday, which is when it became available to me in via 'dnf -y upgrade', and so far so good. I'm still in a wait and see approach. =:)

Hello Friends:


I eventually figured out my issue, and boy this was both obvious and not obvious at the same time. A completely different discussion on a Lenovo forum mentioned updating the BIOS, but for another reason. That got me to thinking, "Let me try that". I did it and the problem hasn't resurfaced since (fingers crossed -- but it's been a while now).

My own description in this post -- which was INPUT and OUTPUT related, and even mentioned BIOS -- did not trigger the thought to do this. Most likely because you usually don't see BIOS updates. But, in fact, there were a few BIOS updates in this case. (._.) I wish I had thought of this many months ago.

Ah, well. I hope this helps someone else. =)

After performing another sudo dnf -y update, which contained a newer kernel 4.11.4-200.fc25.x86_64, things have stabilized (no freezes). But I'm still in wait-and-see mode, and will report back in a few days.

UPDATE-1: The above kernel turned out to be stable. The crashes have disappeared. And after updating to an even newer one, 4.11.5-200.fc25.x86_64, stability continues.

UPDATE-2: The issue has returned, so I was incorrect in the above solution (didn't wait long enough). I'm not sure what it causing this again. It's not the laptop, by the way, because multi-booting into MS-Windows 10 has no issues. So I'll uncheck my answer for now. =:) Will check back if I resolve this later.

sounds like an overheat. my desktop runs warmer in linux than in windows. immediately after it freezes, can you go to bios, and check temperatures?

Possibly. I'll have to check what the BIOS has to offer temperature wise. I'll check that out next time. Thank you. :)

I run 381.22 proprietary. I do not know what the version numbers are on the negativo version, could be a modification. I am on a desktop, so only have the one video adapter. I am running 4.11.4-200 and letting dkms build the kernel modules during the kernel updates. No issues.
