Subject: 2.6.24-rc6: ricoh_mmc woes

Hi folks,

I've got a problem with a Ricoh mmc reader. As soon as I insert a
sd card I get tons of I/O errors. syslog says:

The ricoh_mmc disabler module is installed as a module. udev loads it
at boot time. But AFAICS I get the same errors if ricoh_mmc is removed.

lspci says

# lspci | grep -i ricoh

03:01.3 0880: 1180:0592 (rev 12)
03:01.4 0880: 1180:0852 (rev ff)

Of course the SD card works fine in another PC.

Any idea how to track this down? Please mail
