so What i found is that the stock mi25 vbios had this issue, but the wx9100 vbios did not, I think it has something to do with the MIopen kernels , since it would complain about the 56 cus, but did not do that for the 64 cus enabled with the wx9100, but I don’t know for sure that this is the cause
you can find the applicable miopen kernels, here Index of /rocm/apt/5.4.3/pool/main/m/
your card is a radeon vII so that would be the gfx906 60 cu package, if you don’t have a debian/ubuntu distro, just extract the contents to the applicable directory.
