Description
Downstream issue: https://github.com/JuliaGPU/AMGX.jl/issues/21.
The input matrix in that issue is singular but there seems to be some issue where instead of getting a well-descriptive error message, the more general Fail to get info from cudense is printed.

Research direction
Start by reproducing the singular-matrix input from the linked AMGX.jl issue and trace where the generic Fail to get info from cudense message is produced. Identify the underlying singular-matrix failure and define a descriptive error for that case; done means the reproduction reports the specific problem instead of the generic message.
