If you’ve got it installed, run memtest86 overnight. Random freezes often can be traced to either a few bad spots in RAM or power line fluctuations. There’s not much you can do about the power but you can swap out bad RAM.
journalctl -b only shows the journal since the last successful reboot. If you had to reboot to clear the freeze, the error will be in the previous journal log, not the current one.
This was one of the errors in the Journal.
systemd-coredump[3760]: Process 3757 (vulkandriverque) of user 1000 dumped core.Stack trace of thread 195:#0 0x00007fc0547e405f n/a (/usr/lib/x86_64-linux-gnu/libc-2.27.so)
I will be checking again once I encounter another freeze.
And I am running on my intel i7 8700k integrated GPU at the current moment. Have to wait a bit to get a decent GPU.
Could you run coredumpctl debug vulkandriverque (you’ll need gdb or lldb installed), and then run bt to see a full stack trace of where the error occurred?
