I had an ugly instance of this problem on an EPYC processor. Not sure what it was related to. It all started with errors during package upgrades. sudo apt-get update >> success sudo apt-get upgrade >> segmentation fault The upgrade left several packages in a half-installed state (attach Part 1), and basic os command started to crash (attach Part 2). In the syslog I had "general protection fault: 0000 [#1] SMP NOPTI" with multiple processes, see a detail failure log in attach Part 3 and Part 4. Attach Part 5 lists numerous processes that had the same failure as Part 4. The system load started to climb, from idle, progressively by about 1 point per 3-5 min, until levels like 20-30, at this point it was very difficult to enter and reboot the system. I tried and managed to have it respond with reboot -f but it had the problem still and system did not come up correctly, until we performed a physical shutdown and restart. From then the system seems clean. I corrected the packages by reinstallation, and so far no problem. Very frightening! Can it be related to some problem between Ubuntu and the Ryzen/EPYC technology?
