Debugging laptop that continues to freeze

george55 · 2019-03-20 16:01:12

Very similar to this thread, I experience random but recurring laptop freezes for no clear reason. My journal is clean (as far as I can tell), nothing in dmesg, no error logs that I can find point to the culprit. The laptop will freeze at a random point, and when it does, the screen freezes, mouse and keyboard are unresponsive, sound get stuck on a very short repeat (0.5 sec of audio gets repeated over and over), and all I can do is a hard reset.

I have tried finding a pattern, but this has happened with/without usb devices plugged in, when playing audio/when not playing audio, when using any application ranging from Firefox to vim to thunar. I can't find a common pattern.

I am using i3 window manager, 4.19.29-1-lts kernel (changes from the most recent regular kernel to see if it would help -- it did not). This is a Dell Chromebook running Arch as the sole OS.

Journal: https://pastebin.com/0jsvRApq (this one includes two freezes) --- NOTE: whenever a hard reset happens, I lose some entries in the journal. Here you can see it, "reboot" indicates hard resets. There is < 1 minute between freeze and reset but in the log there are often 2-6 minutes missing...

dmesg: https://pastebin.com/qjfwTnk3

I don't have TLP installed (which was the culprit in the other thread).

Any ideas how I can debug this? I am not sure if this is software or hardware. I have been having some issues mounting my SD card recently and the battery also seems to be degrading. So maybe hardware -- but I can't imagine the dramatic freezes because of this.

spring out as potentially problematic. Run a long SMART test over your drives then check and/or post the output of smartctl -a $device

Thanks. This is a mini sd card that I use to extend my small HD. However, it's encrypted using dm-crypt. Using smartctl doesn't work, not sure if it's because it's an sd card or encrypted.

Output:

Please specify device type with the -d option.

Just one more comment: even though the problem is flaring up again (had 2 freezes in the last 10 minutes), it has _never_ happened when I was playing video. I can be watching a 2 hour long movie and it will not freeze. Other than that, if I use any other application it can very well freeze. I watch videos using VLC. But VLC is not immune... If I listen to music in the background then it may well crash. Only if I am viewing a video full screen with no other application being actively used (they may be open in the background though) have I never had a crash. At least not YET...

Just ran memtester, didn't find any issues.

I ran memtester:
