Re: MMCCAM hang

That makes sense. The threads you posted showed several blocked on IO while
sdhci was resetting. That's going to keep any I/O from happening. I guess
I'm not surprised it's the wrong quirks... Many years ago when I was
playing with a new, somewhat buggy SDHCI PCIe add-in card having the wrong
quirks would cause super weird behavior. In my case, it was an infinite
stream of interrupts...

You should be able to disable the FreeBSD device like any other FreeBSD
device

hint.sdhci.0.disabled=1

we'll probe the device (which for FDT checks the compat settings) and then
never call attach, but instead print a message saying it is disabled.

One can also create an overlay that sets its status to something other than
okay, but that's quite a bit trickier and can't be done on the fly from the
boot loader.
