Hi,
my motherboard and express card slot was replaced in my Dell Vostro 3550. It still does not report
when a card is unplugged (on re-insertion it does realize the change and complains about Surprise removal.
I haven't studied the current bit in detail again with new hardwarte but I believe this is still about
the "Changed:" line in 'lspci -vvvxxx' output which does not change.
I reported the details with the previous hardware and my impression was that for my FireWire and
eSATA card the "SltSta:" *does* change and *does* reflect state of teh slot (with card inserted or out).
Could linux kernel keep its own variablwe to to track changes of the states and ignore the
"Changed: MRL- PresDet- LinkState-" line? This is some kind of introduction to my hardware. ;)

The above "surprise removal" upsets sata_sil24 driver, it does not crash bad complains
badly. I am not sure if there is anything to be changed here, the slowpath warning is
probably valid and desired (SATA port cannot be removed from the system too quickly).
Unfortunately, because the ExpressCard hardware is physically not very advanced, it happens
to me with this express card that it does not hold during insertion into teh slot
and slips out immediately. Hence, the sata_sil24 Oops below.

SATA/IDE, probably take this just as a note. For the pciehp stuff I will eventually provide
