[Sdhci-devel] Ricoh R5C822 on Inspiron 640m: No interrupts

[Daniel Drake]

Hi,

I have a new Dell Inspiron 640m laptop, with this hardware:

02:01.1 Class 0805: Ricoh Co Ltd R5C822 SD/SDIO/MMC/MS/MSPro Host 
Adapter (rev 19)
02:01.2 System peripheral: Ricoh Co Ltd Unknown device 0843 (rev 01)
02:01.3 System peripheral: Ricoh Co Ltd R5C592 Memory Stick Bus Host 
Adapter (rev 0a)
02:01.4 System peripheral: Ricoh Co Ltd xD-Picture Card Controller (rev 05)

I am not getting any interrupts according to the counter in 
/proc/interrupts - its stays 0 no matter which card I insert.

I am using 2.6.17-rc5 with the 9 audit patches.

Any ideas or things I could try?
