# Nvidia Drivers and CPU Stuck

I hope this message finds you well. I am also facing a challenging issue while attempting to install nvidia driver on ubuntu. I am installing a new ubuntu on the Dell PowerEdge T640 server. I have tried Ubuntu 20.04.6 server lts, Ubuntu 22.04 server lts with nvidia-driver-535-server or some earlier versions (525, 515). These drivers are installed by apt. The same, when I try to run nvidia-smi I always get log like “watchdog: BUG: soft lockup - CPU 0 stuck for 22s!” and the process “nvidia-smi” cannot be killed in any way. Sometimes the server will fail to boot and stuck at “load nvidia driver”.

I think my problem is similar to Nvidia Drivers and CPU Stuck but I cannot find a solution.
Thank you in advance for your time and support. I’m looking forward to any assistance you can provide.
