When booting the same hardware via an USB stick into OpenELEC, the card reader is detected and working without errors.

http://bugzilla.opensuse.org/show_bug.cgi?id=899633 --- Comment #11 from Michael from Offenbach Germany --- Checked with kernel 3.18 from kernel/stable, does not work also. I've chatted with Stephan Raue, one of the OpenElec developers, as "config.gz" unfortunately does not exist on OpenElec. I've attached the OpenElec kernel options from Guthub. Stephan pointed me to kernel module rts5208 (Realtek PCIE storage driver). Which is loaded and used on OpenElec with option "y" for kernel 3.13. Which is not loaded into OpemSuse's 13.1 3.11 kernel, but for kernel 3.18, with option "m". But even when I load rts5208 with modprobe, the card reader does not work. Question: Why do I get the dmesg lines: [ 3.315834] sdhci-pci 0000:00:11.0: SDHCI controller found [8086:0f15] (rev e) [ 3.318091] mmc0: SDHCI controller on PCI [0000:00:11.0] using ADMA on OpenElec, where the sdcard later will be deteced as /dev/mmcblk0, /dev/mmcblk0p1 to /dev/mmcblk0p6, and why do I get line like [ 5.817986] sdhci-acpi 80860F14:01: No vmmc regulator found [ 5.817994] sdhci-acpi 80860F14:01: No vqmmc regulator found [ 5.821590] mmc0: SDHCI controller on ACPI [80860F14:01] using ADMA on OpenSuse, kernel 3.18? What is the difference between "PCI" and "ACPI" in the context of "SDHCI controller on PCI" and "SDHCI controller on ACPI"? -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.opensuse.org/show_bug.cgi?id=899633 http://bugzilla.opensuse.org/show_bug.cgi?id=899633#c21 --- Comment #21 from Michael from Offenbach Germany --- Hi Joerg, as advised I've blacklisted sdhci-acpi and run "mkinitrd" after this. No change, sdcard reader still not detected. I additionally looked in my BIOS settings, as I didn't know that ACPI is doing anything more than controlling/managing energy saving levels: "ACPI autoconfiguration" is set to false. As this the only option to avoid hibernation, whch I don't want. There's another undocumented/unknown option "Lock ACPI-legacy resources", which was set to disabled. I've set it to "enabled", but also no change. dmesg-899633-16.08.12.txt attached, as requested. -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.opensuse.org/show_bug.cgi?id=899633 http://bugzilla.opensuse.org/show_bug.cgi?id=899633#c23 --- Comment #23 from Joerg Roedel --- (In reply to Michael from Offenbach Germany from comment #21)

"ACPI autoconfiguration" is set to false. As this the only option to avoid hibernation, whch I don't want.

Okay, thanks for testing this. The sdhci-acpi error messages are gone, but since the PCI devices are still missing, the sdhci-pci driver can't bind to them. We need to find out now why these devices exist under openelec and not under opensuse. Can you, just for testing purposes, try to change the above mentioned BIOS option and see if it makes a difference? One difference between the dmesg files was that on SUSE there appeared S4 in the list of supported sleep states, while it is missing on the openelec dmesg. Also, can you boot openelec again and get the output of 'lspci -t' and attach it here? Thanks. -- You are receiving this mail because: You are on the CC list for the bug.
