Having tried the latest daily mainline kernel debs as of 2012-01-07, I can confirm this problem is still present on my system.
My system is one of the Twinhead H12Y ones that requires the reserve=0xFFB00000,0x100000 I am running 64-bit. These are the relevant lines from lspci 03:06.0 FireWire (IEEE 1394) [0c00]: O2 Micro, Inc. Firewire (IEEE 1394) [1217:00f7] (rev 02) 03:06.2 SD Host controller [0805]: O2 Micro, Inc. Integrated MMC/SD Controller [1217:7120] (rev 01) 03:06.3 Mass storage controller [0180]: O2 Micro, Inc. Integrated MS/xD Controller [1217:7130] (rev 01) These are the relevant lines from load of sdhci-pci, note that I have an Unknown controller version. [ 434.613448] sdhci-pci 0000:03:06.2: SDHCI controller found [1217:7120] (rev 1) [ 434.613476] sdhci-pci 0000:03:06.2: PCI INT A -> GSI 19 (level, low) -> IRQ 19 [ 434.613512] mmc0: Unknown controller version (16). You may experience problems. [ 434.613532] mmc0: no vmmc regulator found [ 434.613582] Registered led device: mmc0:: [ 434.613646] mmc0: SDHCI controller on PCI [0000:03:06.2] using PIO No combination of debug_quirk, etc. I have tried has been able to get past the mmc0: Timeout waiting for hardware interrupt, though I have not been exhaustive. The lack of documentation makes it a little hard to be sure what any of the parameters are for without reading the entire sdhci tree, but none of the obviously named quirks helped. A thought though, is there perhaps a way to interact with this card that does not require interrupts for the transfer? At least as a workaround until this is fixed? ** Tags removed: kernel-unable-to-test-upstream needs-upstream-testing ** Tags added: kernel-bug-exists-upstream -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/892906 Title: SD Card reader not working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/892906/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
