The problem starts already at kernel 6.6, at least at 6.6.52

I also tried to modify: 

drivers/mmc/core/core.c

essentially reverting it back to it's 6.5.5 state:

diff linux-6.5.5-gentoo/drivers/mmc/core/core.c linux-6.6.52-gentoo/drivers/mmc/core/core.c 
554c554,556

doing this I was semi successful, as

mmc0: error -95 doing runtime resume

still showed up, but after around 1 minute of waiting the driver seemed to have recovered and continued working, until failing again a few minutes later. Which causes large long stalls on when trying to use the card.
