I have doubt about supporting MMMapIoSpace() , ... since they are supposed to
be called by the hardware device drivers (e.g. TO map the memory mapped I/O
ports  BARs of those PCI device by the device driver )

lspci -vvvn

If you want a meaningful ntoskrnl.MmMapIoSpace() this is almost a no-go.
One could theoretically implement a userland "kernel address space" emulation
(page faults to trap accesses and emulate them where necessary or use a helper
kernel driver) but that's currently out of the scope of Wine.
File a new bug if you want ntoskrnl.MmMapIoSpace() implemented but it will
probably stay a long time.

I'll mark this one fixed as the reported crashes are gone.
