ubuntu client crash after cifs error

[adahsuzixin]

I mount the truenas shared disk as a client on different servers. The operating system version of the client is Ubuntu 22.04.2 LTS. The client will crash because of cifs error. The error message before the crash is as follows

- client A

We are running an older version of FreeNAS-11.3-U2.1 and the client is a Rocky Linux 9.1 running cifs-utils-6.14-1.el9.x86_64 and we see the client crash as well. Complete lockup of the client requires a hard reset. Similar error as above. Did not see this issue on centos 8.5.2011.
