Public bug reported:

Hi,

I just experienced a frozen desktop, where I could barely move the
mouse, for maybe 30 seconds or more.

When the desktop recovered, I looked at dmesg logs to find these lines:

[  461.937702] NVRM: GPU at PCI:0000:01:00: 
GPU-734060ac-116d-fbbb-1553-d84896b846a4
[  461.937710] NVRM: Xid (PCI:0000:01:00): 31, pid=275, Ch 0000002e, intr 
00000000. MMU Fault: ENGINE HOST0 HUBCLIENT_HOST_CPU faulted @ 0x1_0036d000. 
Fault is of type FAULT_PTE ACCESS_TYPE_VIRT_READ

It looks like a fault from the Nvidia driver.
I'm using the tested one "nvidia-driver-435", installed via the GUI tool.

Could you report this to Nvidia please ?

Thanks
