Do you have a pciconf entry for class=080501 chip=0x2391197b, device
would probably be "SD Host Controller", and if so, is it none_at_pci or 
sdhci_pci_at_pci ?  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.
