Older AMD GPUs that work on x86 are incompatible with RISC-V's Advanced Interrupt Architecture (AIA)
Looks like hardware that implements AIA like SpacemiT K3 are 100% incompatible with older AMD GPUs, at least the ones with the Caicos GPU and potentially others. This issue only seems solvable with a revision in the AIA standard, which would take years to take effect in new RISC-V hardware. RISC-V ecosystem contributors seem to suggest not using such ancient cards.
