Hmm, so that 03:00.1 device doesn't seem to show up at all? I think
that these Marvell 9123 cards have a PATA controller integrated as
well, maybe that has something to do with the issue?
Yes, strange isn't it? There are no other add-on cards in this system, for
what it's worth, and the SATA card is definitely failing, so it does look
like it might be implicated. I have four such boxes, all of which show
identical symptoms.
Is it the same model of add-on card?
This controller apparently has both a SATA and PATA controller on it.
The PATA portion doesn't seem to be showing up in lspci, but obviously
the BIOS saw some sign of it - and if the IOMMU reporting can be
believed, it's trying to do a read request for some reason..
Is there anything I can do to debug this better?
