Automatic DKMS installation does not detect different versions of the same module during upgrade.

[SahorSs]

If you add several versions of one module and the update of one of them fails, the update of the remaining modules will not start.

Which version of dkms are you using? We had a bunch of changes with 3.0.11 - would be great if know if those fixed or regressed your use-case. If you can you try 3.0.10 and 3.0.11 that would be great.

AFAICT autoinstall picks only the latest version of the dkms module(s) - that's intentional, since *the newer versioned module should support both older and newer kernels. Alternatively you can easily end up with old_module + new_kernel, where the former cannot build/is buggy with the latter.

What is your use-case for a having newer version of the module, yet not building/using it?
