With this patch applied I end up with: [ 2.437316] Waiting for root device /dev/mmcblk0p2... [ 4.428192] mmc0: card never left busy state [ 4.432647] mmc0: error -110 whilst initialising SD card I noticed this after I disabled lock debugging and tracing (syscall tracing was enabled). Enabling both again makes the error go away. With debugging + tracing disabled (so the error pops up) and git bisect I get this commit (daebabd57) reported. A diff between a good/bad bootlog (with lock-debug + tracing switched off): | smartreflex smartreflex.0: omap_sr_probe: SmartReflex driver initialized | smartreflex smartreflex.1: omap_sr_probe: SmartReflex driver initialized | hsusb2_vbus: disabling | VPLL2: disabling | VUSB3V1: disabling |+VDAC: disabling |+VAUX3: disabling | Waiting for root device /dev/mmcblk0p2... |-mmc0: host does not support reading read-only switch. assuming write-enable. |-mmc0: new high speed SDHC card at address 1234 |-mmcblk0: mmc0:1234 SA04G 3.63 GiB |- mmcblk0: p1 p2 p3 |-BTRFS: device fsid 2e050bbb-1520-425e-a215-1e5bf865c7dc devid 1 transid 496 /dev/root |-BTRFS info (device mmcblk0p2): disk space caching is enabled |-BTRFS: detected SSD devices, enabling SSD mode |-VFS: Mounted root (btrfs filesystem) readonly on device 0:13. |-devtmpfs: mounted |-Freeing unused kernel memory: 216K (c051a000 - c0550000) |-BTRFS info (device mmcblk0p2): disk space caching is enabled |- |-Please press Enter to activate this console. |+mmc0: card never left busy state |+mmc0: error -110 whilst initialising SD card reverting this commit on top of -rc3 makes mmc0 work again.
