Sorry for the late reply. Among the error logs you provided, the message "handle_hca_cap failed" caught my eye, so I looked it up on Google. There were related improvement patches as follows.

And, pci_irq.c containing this content exists only in the SA6400 model using kernel 5.

SA6400 supports graphics acceleration of Intel 11th generation or higher iGPU, enabling transcoding. Device mapping is easy based on device-tree. HBAs are also supported. If it's a model that suits your purposes, we recommend giving the SA6400 a try. This model is currently in a significant stabilization phase.
