Getting regular system freezes
Hi,
I'm using Debian Stretch, currently with the Cinnamon desktop (3.2.7).
I get regular system freezes, and often have to hard reboot (hold down the power button on my laptop) to restart. Sometimes, sysreq with REISUB manages to do it.
I have no idea what's causing this or what to do about it and I haven't noticed it correlating with any particular program or activity (although I guess like most users I pretty much always have a browser open).
Any idea what I could do to diagnose/ fix this?
The laptop is a Clevo W950TU. Currently Debian 9.3, Linux 4.9.0-5-amd64, although I've been experiencing this problem for a few months - probably since the upgrade from Jessie.
Cheers

Did you try switching to a TTY to eliminate a simple graphics failure?nickmdowson wrote:often have to hard reboot
What is your graphics hardware and drivers?
Code: Select all
lspci -knn | grep -A2 '\''[030[02]\]'

Re: Getting regular system freezes
It doesn't let me switch to a tty - I always try this first to see if I can recover it.

I'll try enabling persistent logging now, thanks.

Re: Getting regular system freezes
The system specs indicate that it would have an Intel Bay Trail processor.nickmdowson wrote:I get regular system freezes,... The laptop is a Clevo W950TU.
Try a search with, Intel Bay Trail and intel_idle.max_cstate, keywords. You should find quite a bit of information that might be helpful, at least worth checking.

Re: Getting regular system freezes
I'm sorry, I looked up the specs on the manufactures web site. I do know that sometimes components are changed without updating documentation and I should have mentioned the possibility.nickmdowson wrote:My system specs say 'Intel Pentium CPU N5320'
If it had been a 3520 it would be a Bay Trail.
What did you get from H_o_a_S's advice to look at the journal? That seemed to be a sane way to troubleshoot.

Re: Getting regular system freezes
No worries, I think it might be a customised version of that model. I've enabled persistent logging now, so will check that again after the next freeze!
Cheers!

Try REISUBO.nickmdowson wrote:Sometimes, sysreq with REISUB manages to do it.
Is the system freezing? Or is it just X? What I'm getting at is that the screen, mouse and keyboard freeze but the kernel is functioning happily underneath. That's what Head_on_a_Stick was suggesting. Because you can sometimes shut it down with REISUB I suspect this is the case.

Re: Getting regular system freezes
I'll try REISUBO next time - I'm not sure how to tell if it's X or the kernel, but it's generally entirely unresponsive.
Re: Getting regular system freezes
Consider that you may have an hardware problem. Flaky video cards tend to work most of the time but a big load (games, movies, huge documents) can stress them.
Search the Internet for your hardware components. Look for reports that look like yours. I once discovered that a motherboard I had always failed as mine was failing. Bingo.
When was the last time you blew the dust out of your computer? A sticking fan can cause overheating. Try re-seating memory cards.
Take notes.

Re: Getting regular system freezes
Don't think it's a hardware problem as it wasn't happening with Debian Jessie - and it doesn't seem to correlate with doing graphics-heavy tasks. Hope not anyway!
Re: Getting regular system freezes
Use a process of elimination. Check the logs before you crack it open. The previous xorg log after you reboot will let you eliminate X, or maybe give you a hint. It's almost always hardware related, heat, video config or a bad drive/cable has done this to me in the past. Reseating ram does seem to have a lot of mojo sometimes, but I can't really prove it.nickmdowson wrote: Any idea what I could do to diagnose/ fix this?
