System Freeze with "unable to handle page fault for address"

We have a machine with several A5000 with kernel 5.15.0-101-generic and NVIDIA driver 535.161.07. It ran software for few days stably and all of sudden freeze, A reboot hot fixed the issue and there is no way for me to actively test it. All I got is some log (see attached):

kernel.log (3.3 KB)

What would cause this ? Is this a for sure hardware failure ? or driver kernel issue or software related ?

There is no memory, GPU usage or CPU, or disk usage issues from the stats.
