I see a endless loop in following code of sdbus.sys with 16-bit PCMCIA card.
Does any one know what it is waiting for? and why it failed? Thanks.

Your card was unplugged or reset. All registers are read as FFFF. This is a
common mistake to fail to check for the device unplug.

Thank you very much, Alexander.
This happens when resuming from S4, that means the card has not been powered
on? Thanks.
