I can report success as well on a 504x. However it only works without 
MSI, with MSI I get the same insmod blocked in D state as before.

I'll try some torture tests with the 2 disks currently attached (on
port 1 and port 3), but I'll have to revert to a non-DEBUG libata to 
get rid of the logging...

Many thanks!
