Your second example is irrelevant right? There you are doing a matrix vector multiplication. What seems to be missing is a multiplication with a scalar using the mul! interface. This works for arrays in LinearAlgebra, but a method seems to be missing for CuArrays. I think this is a CUDA.jl issue.

However, it would arguably be good to have dedicated tests for testing KrylovKit.jl - CUDA.jl interoperability.

I thought the second example was showing that mul! works on CuArrays in general, so I don't know why KrylovKit requires making changes to mul! in order to work.
I can file this under CUDA.jl if you think that's more appropriate, but I don't know how to reproduce the issue without using KrylovKit.

Because it's another method signature, you are illustrating
mul!(::CuArray, ::CuArray, ::CuArray)
the error is from
mul!(::CuArray, ::CuArray, ::Number)
from krylovkit.jl.

Ah, yes. Clearly. Thanks for pointing that out. I'll file a CUDA ticket and you can decide if you want to close this one.
Thanks!

Works on Julia Version 1.6.2, CUDA toolkit 11.1.1.
