description = """In U-Boot CI, we started to update from v8.2.0 to v9.2.3 and found that the sifive_unleashed target was failing to boot from SD card in our tests (we also test via SPI and this is fine). I have bisected the problem down to commit [da954d0e ("hw/sd/sdcard: Add spi_cmd_SEND_CSD/CID handlers (CMD9 & CMD10)")](https://gitlab.com/qemu-project/qemu/-/commit/da954d0e32444f122a41c24948d4d1c718bf66d4).

When running QEMU we see the following output in the failure case as the only output:
```
U-Boot SPL 2025.07-rc1-00033-gad60d9792896 (May 01 2025 - 17:08:34 +0000)
