My #linux laptop (#Thinkpad E590) #freezes in unpredictable situations. I've had this in various reinstalls of different Linux distributions (#ubuntu, #fedora, #debian). The EFI hardware test does not indicate any faults, neither did memtest. Can anyone give me a hint for finding out what's wrong? I suspect a hardware issue as I've changed the software stack multiple times, still I'd like to know what's wrong. I don't really know what to google for.

Boosts appreciated.
