Can you please try attached patch which disables the serial MUX and ATI card?
If it works for you and if we backport it to all kernels and if we revert palo to use ttyS0 for all machines we might be good.
I hacked on the change but I couldn't get it to work. As far as I can tell, the quirks aren't being called.
Tried EARLY, HEADER and FINAL. I think the ids are correct.
Strange. The attached patch does work for me on panama up until boot.
Haven't tested what lspci reports afterwards...
