[Bug 41211] sdhci: Nothing happens when a card is inserted

[Richard Laager]

Public bug reported:

Affects: linux-source-2.6.15 (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed


Description:
I'm trying to get a card reader working on my laptop. I see that the
sdhci driver loads, and provides a REGISTER DUMP. I also see "mmc0:
SDHCI at 0xd2007800 irq 74 DMA". But, I don't see a block device in /dev
and nothing happens / nothing appears via dmesg when I insert a card.

I thought perhaps having a newer version of the sdhci driver would help,
so I copied it into a kernel tree. I had to pull in some MMC changes. I
got stuck as there seems to be some new uevent stuff in a bus_type
struct.

Any ideas on what I should try next?"
