kernel.log s2idle without and with sdhci_pci module

S2idle sleep on TUXEDO InfinityBook Pro 14 Gen9 Intel laptop with GL9767 SD card reader consumes 6 watts. Intel Core Ultra 7 155H is not entering s0ix properly. If I blacklist sdhci_pci in /etc/modprobe.d/blacklist.conf then the device sleeps with 1.2 watts (this is not super good, but OK). Unfortunately unloading and reloading does not work either. Once the module has been loaded, the high power consumption remains, even after a rmmod.

I tested this behavior with linux mainline 6.11.0-rc7, 6.11.0-rc7-next-20240909. Kernel mmc/next does not work either.

I also used Intel S0ix Selftest Tool and it blamed the GL9767 SD card reader.
