Thanks for testing. However the approach was basically rejected in this thread:
[PATCH] PCI MSI: allow alignment restrictions on vector allocation

So we still need an upstream solution.

I am curious what Qualcomm have to say about their hardware corrupting
the MSI Message Data value. Is there any news on them submitting the
MSI support patch?

Separately we have the option of seeing if Intel can help us unblock
the legacy interrupt (assuming it was simply blocked by the BIOS), or
adding an interrupt-polling fallback path to ath9k.
