Bug ID: 277884
Summary: RPi4: mmc broken with GENERIC-NODEBUG
Product: Base System
Version: 15.0-CURRENT
Hardware: arm64
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern

dmesg from working boot
i have two RPi4s, one 2GB and one 4GB, using SanDisk 16GB SD cards:
mmc0: <MMC/SD bus> on sdhci_bcm0
mmc1: <MMC/SD bus> on sdhci_bcm1
mmc0: No compatible cards found on bus
mmcsd0: 16GB <SDHC SC16G 8.0 SN 4D52ABA7 MFG 05/2022 by 3 SD> at mmc1
50.0MHz/4bit/65535-block
these are both running 15.0 as of 312a05c39e5fd79b37ee6f922462232797f56a2a. i
tested with both the current sysutils/rpi-firmware from ports (20230405), and
the firmware from the current 15.0 binary snapshots.
when booting with GENERIC, both RPis work fine. when booting with
GENERIC-NODEBUG, the SD card won't attach and mountroot fails. this is
reproducible. the problem appears to be specific to mmc, because if i put the
SD card into a USB card reader instead, both systems boot fine with either
kernel.
i don't have an easy way to access dmesg on a failed boot, but i did notice it
printed the error "DMA error 4 on CH5", relating to the mmc controller.
full dmesg from one of the systems on a working boot is attached.
