Why do systems report "jitterentropy: Initialization failed" errors during boot?
Issue
Red Hat Enterprise Linux 8 servers occasionally report a failure to initialize the jitterentropy driver during boot:
[root@localhost ~]# dmesg | grep -i fail
[ 4.121091] jitterentropy: Initialization failed with host not compliant with requirements: 2
Environment
- Red Hat Enteprise Linux 8
- Intel or AMD x86 server
- The HPE DL385 Gen10 with AMD 2nd generation EPYC (Rome) CPUs seems to report this error more frequently than other systems, but all x86 servers (both Intel and AMD CPUs) can experience this error.
