Hello
My port multiplier capable eSATA Express Card refuses to talk to my
external HDD box (2 HDDs, JBOD mode).
Inserting the card into the Express Card slot looks normal:

Turning on the external box results in lots of errors:

Which kernel version is this? Can you test latest git?
Sorry, I forgot the kernel version.
It is 2.6.31-14 (Ubuntu 9.10 amd64). I will try the latest vanilla kernel.
The card is able to talk to a single disk enclosure without problems, so
I would assume that either Port Multiplying or my external 2-disk box
is at fault here.
Regards, Peter.
