If sdhci_pci attached, there would be dmesg output for it, and I'm curious whether any irq-related error showed up when it attached. The only change I can find that might have some effect is a switch to MSI-based interrupts some time ago. That was MFC'd to 10-stable in r271051, and that's very close to range cited in that PR. It might be worth trying to set hw.sdhci.enable_msi=0 in loader.conf and see if it makes a difference. -- Ian
