Remove 'quiet' from RPi cmdline.txt so kernel probe messages are visible on HDMI. Add comprehensive diagnostics to the data device error path: dmesg for MMC/SDHCI/regulators/firmware, /sys/class/block listing, and error message scanning. This will reveal why zero block devices appear despite all kernel configs being correct. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
