First of all, since the page is registered in the ExMem zone, it seems possible to test the CXL memory.
However, It is strange that pages are registered in the ExMem zone when the cxl_pci module is not loaded, because the CXL memory registration is performed in cxl_pci.ko.
Can you provide dmesg full log for the above situation? Then I think a more detailed analysis is possible.

Can you provide your email address for sending the dmesg log just to you?

Thank you for sharing the experiment result.
Your feedback is valuable for us to make SMDK robustness.
In a few days, we will update SMDK kernel repo, https://github.com/OpenMPDK/SMDK-linux-cxl, that clones tovalds for the error handling logic.
Furthermore, SMDK repo will update the logic on next offcial release.
Please feel free to contact us for any upcoming inquery.
