I have recently run kernels 3.11, 3.15, 3.16. The problem did not exist with kernel 3.11 and I first saw issues in kernels 3.15 and 3.16. I did not test kernels 3.12, 3.13 or 3.14. So the problem started between kernel 3.12 and 3.15. Yes, the card reader works without the r592 module. I have now blacklisted both r592 and r852 and there are no mention of either in the kernel logs at startup or when I plug the card in. Also, the hwinfo command indicates that both modules are not active even when the card is inserted during which I am able to browse the card. I am adding another hwinfo output file with r592 and r852 blacklisted. This file was generated with the SD card inserted and working. The hwinfo output says that both R592 and r852 are not active. However, there are two other Ricoh devices: Device 32: PCI 301.0: 0c00 FireWire (IEEE 1394) (OHCI) Model: Model: "Ricoh R5C832 IEEE 1394 Controller" Driver: "firewire_ohci" Device 33: PCI 301.1: 0805 SD Host controller Model: "Ricoh R5C822 SD/SDIO/MMC/MS/MSPro Host Adapter" Driver: "sdhci-pci" So, should I also blacklist both firewire_ohci and sdhci-pci? Thanks, Gordon PS: As an FYI, I am now running OpenSUSE 13.2. Previous to three days ago, I was runing OpenSUSE 13.1. I don't know if it matters but I thought that I should mention this.
