This is a warning that you can ignore, it's been fixed in the latest

try that and see.

Greg,

Ok, just tried rc3 and it's fixed the 1st OOPS.

But I'm still seeing the "ataX" incrementing from ata7 to ata8, ata9
... after taking out and putting back the card. It seems the interface
is still not shutting down properly. ... Any command to shutdown it
down gracefully?

The ataX number incrementing is normal (it always increments when an ATA host is initialized, it doesn't appear the numbers get reused). The other messages are the expected result when you surprise-remove the card. I think there should be a way to trigger the hotplug code to disable the device before you eject it, but I'm not sure what that is supposed to be - maybe echo 1 to /sys/device/pci_somethingorother/remove ?
