I have a HP6910 laptop, and I use Fedora in this laptop since Fedora 10. The Ricoh MMC/SD host works fine in versions 10 and 11. But after I install the Fedora 12 the Ricoh MMC/SD host doesn't works.
[root@oxygen ~]# lspci |grep Ricoh

[root@oxygen ~]# dmesg |grep ricoh
ricoh-mmc: Ricoh MMC Controller disabling driver

ricoh-mmc: Ricoh MMC controller found at 0000:02:06.4 [1180:0843] (rev 10)
ricoh-mmc: Controller is now disabled.
I try to load modules ricoh_mmc, mmc_core, tifm_core and tifm_7xx1. But when I insert the card, nothing happen. I watch the /etc/messages file and nothing is printed when the card is inserted.
This hardware is not suported by Fedora 12?
