Comment 0 for bug 1995966

I have Ubuntu 22.10 (uname -a says 5.19.0-23-generic #24-Ubuntu SMP PREEMPT_DYNAMIC Fri Oct 14 15:39:57 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux) on Lenovo P14s laptop.

There is built-in SD card reader, which does not work. i e., when I insert SD card, it is not mounted or recognized at all.

Please note this is not a problem of the SD card, because this SD card works on older Lenovo laptop (with different SD card reader) with Ubuntu (so it is not some "special", incompatible SD card).

    Subsystem: Lenovo RTS522A PCI Express Card Reader [17aa:5094]
    Kernel driver in use: rtsx_pci
    Kernel modules: rtsx_pci

lsmod | grep rtsx_pci says:
rtsx_pci_sdmmc 36864 0
rtsx_pci 106496 1 rtsx_pci_sdmmc

I guess it is a kernel problem? Or there is another solution?
