kernel tried to execute NX-protected page - exploit attempt

[Martin Gerdzhev]

On ubuntu 20.04 I have been plagued by soft/hard lockups on my ryzen 5 3600 for a while now.
This one is a new error however that led to a series of soft/hard lockups. See attached log.

Changing status to "Confirmed" as requested in comment #3

[Kai-Heng Feng (kaihengfeng)]

The first one is caused by nvidia driver.

The version isn't up-to-date:
[ 6.157480] NVRM: loading NVIDIA UNIX x86_64 Kernel Module 435.21 Sun Aug 25 08:17:57 CDT 2019
Can you please try newer version like 440 or 450?
