sdcard not functional on NUC7PJYH

    Resolved - looks like a kernel/driver bug, as per here: 204003 – RTS5229 built in card reader not detected after Linux 5.0.x

    Using a Intel NUC7PJYH with version 9.2.3, and everything is amazing and great... except for the sdcard reader. Flashed latest Intel BIOS, verified that card reader is set to active in the BIOS.

    SDcards do not seem to be seen at all. Inserting a known-good card results in zero response - nothing in dmesg or otherwise. Known-good means that it works in another box running Ubuntu.

    I'm kind of confused as what driver should be loading - lspci -v gives the following...

    Code
    00:1c.0 SD Host controller: Intel Corporation Celeron/Pentium Silver Processor SDA Standard Compliant SD Host Controller (rev 03) (prog-if 01)
DeviceName: Onboard - Other
Subsystem: Intel Corporation Celeron/Pentium Silver Processor SDA Standard Compliant SD Host Controller

Capabilities: [90] Vendor Specific Information: Len=14 <?>

    But there's also this...

    Code
    01:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTS5229 PCI Express Card Reader (rev 01)
Subsystem: Intel Corporation RTS5229 PCI Express Card Reader

    lsmod shows neither.

    Any suggestions how to troubleshoot? Anyone have this hardware running?
