I see that rtsx was added to GENERIC.  Might have been premature.

The only thing I can recommend is to install with the SD card reader
disabled in the BIOS.

It may be the case that rtsx still works even if the card reader is
disabled in the BIOS.  That's the first thing I would try out.

If that fails then generate a kernel with rtsx as a module rather than
it being hard coded into the kernel.

You could then re-enable the SD card reader in the BIOS and load the
module to check whether the SD card reader works or causes a panic
when the moduke is loaded.  This approach might make it possible to
get a crash dump if a problem occurs.
