Minimum supported Linux kernel versions

[rd-pck]

I'm in the difficult position of trying to improve .NET compatibility on very very old and unsupported hardware. I am not in a position to change this hardware.

The hardware in question excusively supports a very very old version of Ubuntu. This is because it requires a custom kernel that has received no development since the release of that version of Ubuntu. Essentially, we are locked by hardware to this custom kernel and the corresponding release of Ubuntu.

We run a .NET program on that hardware through a very very old version of Mono. I'm looking to see if I can get a newer version of Mono running instead, so we can run newer (perhaps even supported) .NET versions and dependencies.

Is there any list/table of minimum supported kernel versions for each Mono release? What other dependencies of Mono (libc for example) do I need to be aware of before attempting to update?
