I'm having persistent problems with Evolution fetching and reading Pop mail from a local ISP. Every time I connect to a different folder, set a filter, or click on send/receive, there's a 24-26 second pause before the result is displayed. I see the same pauses with existing, already downloaded mail. Thee pauses affect the entire system. When I run "journalctl -fa" in a Terminal window I see the following:

Jan 15 23:01:34 tiger.protogeek.org kernel: Lockdown: pmdakvm: debugfs access is restricted; see man kernel_lockdown.7

When I try to view man kernel_lockdown.7, I get "No manual entry for kernel_lockdown.7"

This is a fully-updated F31 system. Evolution v3.334.2-1.fc31.

Has anyone else encountered pauses like this with Evolution?
