Kernel Panic with 9.2.8

[AleksZimin]

Hello,

We are experiencing a critical issue with DRBD 9.2.8 running in a 5-node cluster environment. Occasionally, several servers in the cluster undergo unexpected reboots. In one instance, all servers rebooted simultaneously. Most recently, we encountered situations where servers rebooted, and we were able to capture full Call Traces for these incidents.

First Incident Call Trace:
