8devices RED bean does not work

[astrand]

We are trying to make https://www.8devices.com/products/red-bean work with ath10k. This device is based on QCA9733. The PCIe "BLACK bean" works OK, but we need SDIO. Firmware is available here:

https://github.com/8devices/qcacld-2.0/tree/CNSS.LEA.NRT_3.0/firmware_bin/sdio
and
https://github.com/8devices/qcacld-2.0/tree/caf-wlan/LNX.LEH.4.2.2.2/firmware/sdio

Details will follow.

With the latest code on the v5.4-ath10k-sdio branch, the kernel crashes when card is inserted:
