Linux version 4.15.0-72-generic: [Kernel panic - not syncing: Fatal exception in interrupt]

[Yushan Zhang]

The server was not responding today, but it was running last night. Currently I have no idea if any running application has caused the problem. After I rebooted it, I have looked through journalctl and found the following lines:

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.
