After running for several hours at seemingly random times my laptop freezes, the screen is stuck and is unresponsive to any input from mouse or keyboard.
I am running Ubuntu 20.04 with Regolith 1.6, some help diagnosing the problem would be really appreciated, the crash was at 16:27:05. Things I have tried:
- run LENOVO BIOS hardware checks for all components including CPU, MEMTEST, FAN, MOTHERBOARD, and all tests passed.
- Updated to latest firmware for Lenovo with
sudo fwupdmgr get-updates and sudo fwupdmgr install N2WET34W.cab
- checked
ls -l /var/crash, and there are no crash logs
- checked
/var/log/syslog, there were no errors, and the last log message was two minutes before the crash happened, does not seem relevant:
Mar 1 16:25:01 x1 CRON[362611]: (root) CMD (command -v debian-sa1 > /dev/null && debian-sa1 1 1)
- checked
/var/log/kern.log, the last message was about 45 minutes before the system came unresponsive.
Mar 1 15:43:14 x1 kernel: [ 9675.073687] perf: interrupt took too long (3170 > 3133), lowering kernel.perf_event_max_sample_rate to 63000
- I have reinstalled the system from scratch, same OS Ubuntu 20.04 and desktop environment Regolith 1.6, in the hope this would stop the issue, but still the system becomes unresponsive after some hours of use.
It seems odd that this does not happen under any particular load, it seems to happen after some hours of uptime, and all hardware checks passed.
I am running out of ideas here to get to the bottom of this, some help would be really appreciated. Thank you
Also my RAM usage is not exccessive i.e.:
>>> free -h
total used free shared buff/cache available
Mem: 7.4Gi 1.9Gi 2.6Gi 464Mi 2.9Gi 4.8Gi
Swap: 9Gi 0B 9Gi
