8686 sdio - don't get first interrupt

Hi,
I've got a Marvell 8686 with an SDIO interface using a Conexant mmc/sdio
driver. I can successfully load the firmware. When I send the first
command to the host, I don't get an interrupt. It times out and resends
the command, and I immediately get an interrupt. I then read out the
reply to the first command, and the sequence numbers don't match.
>From this point on, every command times out and resendsreads out a reply
to with a non-matching sequence number, because there is always a second
reply because they all timeout.
It might be livable, but the scan command causes the marvell part to
stop responding entirely, and I suspect it has something to do with the
fact that we end up issuing every command twice.
Has anyone seen this type of behavior before? I suspect it's a problem
in how the SDIO driver is initialized, but am hoping someone's been down
this road before.
What follows is the libertas debug output from the point where the
firmware is loaded until a few packets have been processed.
Thanks,
Charlie
