Hello,
it will be a long way until TAGES drivers really begin to talk. This requires a considerable amount of additional infrastructure and rethought of current design. Many ntoskrnl API are just stubs - doing nothing.
One of the main problems is that Wine has to emulate the concept of "kernel" address space vs. user address space mappings somehow (out-of-process context).
This specific failure is due to IoAllocateMdl() being a stub:

it's now implemented.
