I have this in pciconf output:

And my SD-card controller is not working anymore (it worked on
on the same laptop year or two ago). Do I need to load some kld to
it working, or support for this controllers was dropped altogether
some reason? I have mostly vanilla GENERIC at r296772, but it
stopped to work much earlier.


Do you have a pciconf entry for class=080501 chip=0x2391197b, device
would probably be "SD Host Controller", and if so, is it none@pci or
sdhci_pci@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

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.

For what it worth, I also boot with hw.sdhci.debug=1 and got this:
