RHEL 7.7 + 430.52 : random kernel crashes

Is this an actual crash, or is it just a backtrace that the kernel prints when a memory allocation fails? The linked thread says “kernel panic” in its title but the message just looks like a warning rather than a panic.

If I’m decoding the backtrace correctly, the nvidia-modeset kernel module is trying to allocate a very small amount of memory and that is failing. The driver won’t be able to function if memory allocations are failing, but it should fail gracefully.

Does the problem still occur with the latest driver and/or kernel? The 3.10 kernel was released in August of 2014 so it’s pretty old at this point and it’s possible that this is a kernel bug that has since been fixed.

The 3.10.0 version string in RHEL7 is only because RedHat doesn’t rebase within a major RHEL version. But most kernel bugs are fixed on a regular basis with ‘backports’. I am sure NVidia engineering is aware of this since they are working with RedHat for RHEL support on the Tesla vGPUs
