I narrowed down the patch to this merge. https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=e79ab194d15e1baa25540cb9efaf2a459cf4bc32 Using the same boot parameters, I can boot the 4.9.y branch, so I don't think it's my SD card or my boot parameters. I need to go checkout this branch and bisect it to identify what causes a failure to boot over SD card. If anyone has already started this, can you let me know, I don't want to double efforts. Here is the log: [stuff deleted] VDCDC1: incomplete constraints, leaving on mmc0: new high speed SDHC card at address b368 mmcblk0: mmc0:b368 00000 3.75 GiB (ro) mmcblk0: p1 p2 VDCDC3: incomplete constraints, leaving on LDO1: incomplete constraints, leaving on LDO2: incomplete constraints, leaving on VFS: Cannot open root device "mmcblk0p2" or unknown-block(179,2): error -30 Please append a correct "root=" boot option; here are the available partitions: 0100 32768 ram0 (driver?) b300 3931136 mmcblk0 driver: mmcblk b301 208230 mmcblk0p1 01344f9c-01 b302 3720600 mmcblk0p2 01344f9c-02 Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,2) CPU: 0 PID: 1 Comm: swapper Not tainted 4.10.0-rc1 #1 Hardware name: DaVinci DA850/OMAP-L138/AM18x EVM Backtrace: [<c000d5d4>] (dump_backtrace) from [<c000d87c>] (show_stack+0x18/0x1c) r7:c1bba000 r6:c1ff0740 r5:c0594268 r4:00000000 [<c000d864>] (show_stack) from [<c020d2c4>] (dump_stack+0x20/0x28) [<c020d2a4>] (dump_stack) from [<c0087d50>] (panic+0xc0/0x240) [<c0087c94>] (panic) from [<c051a31c>] (mount_block_root+0x1b0/0x298) r3:00000000 r2:00000000 r1:c182fea0 r0:c04a8d24 r7:c1bba000 [<c051a16c>] (mount_block_root) from [<c051a5f8>] (mount_root+0xf8/0x124) r10:00000000 r9:c05195e8 r8:c0593f00 r7:c0593f00 r6:c0593f24 r5:c055416c r4:0b300002 [<c051a500>] (mount_root) from [<c051a788>] (prepare_namespace+0x164/0x1c4) r8:c0593f00 r7:c0593f00 r6:c054286d r5:c0593f24 r4:c0542858 [<c051a624>] (prepare_namespace) from [<c0519e98>] (kernel_init_freeable+0x194/0x1e0) r6:0000006b r5:c0542834 r4:00000008 [<c0519d04>] (kernel_init_freeable) from [<c041ee44>] (kernel_init+0x10/0x104) r10:00000000 r9:00000000 r8:00000000 r7:00000000 r6:00000000 r5:c041ee34 r4:00000000 [<c041ee34>] (kernel_init) from [<c000a4f0>] (ret_from_fork+0x14/0x24) r5:c041ee34 r4:00000000 ---[ end Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,2) -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
