Re: dmesg spam: ahcisata0 port 1: active 2 is 0x40000001 tfd 0x2051

TFES usually means an unsupported command was sent to the device, or a
command was sent while previous was finished.

Could you please try to figure out what is the command sent to the cd0
device just before that error? It should be possible to turn the debug
messages on via the ahcdebug_mask variable in ddb, set it to DEBUG_XFERS

It could also be asynchronous notification from the device, which gets
mishandled as error. I see both your and Martin's device supports them
(SNTF capability). If there is no preceding command, it could be this.
