Hi there, I am trying to get sdhci-pci driver to work with the following hardware: $ sudo lspci -s 03:00.1 -v -nn 03:00.1 SD Host controller [0805]: Broadcom Limited BCM57765/57785 SDXC/MMC Card Reader [14e4:16bc] (rev 10) (prog-if 01) Subsystem: Broadcom Limited BCM57765/57785 SDXC/MMC Card Reader [14e4:96bc] Flags: bus master, fast devsel, latency 0, IRQ 17 Memory at c1820000 (64-bit, prefetchable) [size=64K] Capabilities: [48] Power Management version 3 Capabilities: [58] MSI: Enable- Count=1/1 Maskable- 64bit+ Capabilities: [ac] Express Endpoint, MSI 00 Capabilities: [100] Advanced Error Reporting Capabilities: [150] Power Budgeting <?> Capabilities: [160] Virtual Channel Kernel driver in use: sdhci-pci Kernel modules: sdhci_pci I am using a MacBookPro10,1. I cannot get the driver to work when using a SDHC Samsung Evo 16GB (placed inside a card reader), it always report the following (1). If I now place the card onto a USB reader (USB-HUB reader) then everything is fine (tested using f3: f3probe). Are there any options I can switch to make the driver more tolerant with my hardware ? Thanks Current system is Debian stable with kernel 4.14 (backport), modinfo returns: $ /sbin/modinfo sdhci-pci filename: /lib/modules/4.14.0-0.bpo.2-amd64/kernel/drivers/mmc/host/sdhci-pci.ko license: GPL description: Secure Digital Host Controller Interface PCI driver author: Pierre Ossman <pierre@xxxxxxxxx> alias: pci:v*d*sv*sd*bc08sc05i* alias: pci:v00001022d*sv*sd*bc08sc05i* alias: pci:v00001217d00008621sv*sd*bc*sc*i* alias: pci:v00001217d00008620sv*sd*bc*sc*i* alias: pci:v00001217d00008421sv*sd*bc*sc*i* alias: pci:v00001217d00008420sv*sd*bc*sc*i* (...) alias: pci:v00001524d00000551sv*sd*bc*sc*i* alias: pci:v00001524d00000550sv*sd*bc*sc*i* alias: pci:v00001180d0000E823sv*sd*bc*sc*i* alias: pci:v00001180d0000E822sv*sd*bc*sc*i* alias: pci:v00001180d00000843sv*sd*bc*sc*i* alias: pci:v00001180d00000822sv*sd*bc*sc*i* depends: sdhci,mmc_core intree: Y name: sdhci_pci vermagic: 4.14.0-0.bpo.2-amd64 SMP mod_unload modversions (1) [ 220.210842] mmc0: Tuning timeout, falling back to fixed sampling clock [ 220.210934] mmc0: new ultra high speed DDR50 SDHC card at address 59b4 [ 220.219075] mmcblk0: mmc0:59b4 00000 14.9 GiB [ 230.362858] mmc0: Timeout waiting for hardware interrupt.
