A PowerEdge R410 that was working fine for years started freezing up last week. It's running Ubuntu 20.04 and sometimes it will come back. When it did on a most recent freeze, the dmesg log shows the following:

Any idea how to troubleshoot or other suggestions?

  • Typically Dell server have a hardware event log in their BIOS that e.g. contains ECC RAM errors and other failure messages. In case of problems that would be the first log to check.

  • agree go to bios and use the hw diagnostic, this is how the dell support would also ask first.
