The problem is still there in 3.17-rc2. 3.16 does not have the
problem. Messages are still similar:
mmc0: new high speed SDHC card at address b368
mmcblk0: mmc0:b368 USD 7.45 GiB
mmcblk0: p1 p2 p3 p4
VFS: Cannot open root device "mmcblk0p2" or unknown-block(0,0): error
-6
Please append a correct "root=" boot option; here are the available
partitions:
b300 7822336 mmcblk0 driver: mmcblk
b301 102400 mmcblk0p1 00082434-01
b302 1048576 mmcblk0p2 00082434-02
b303 1024 mmcblk0p3 00082434-03
b304 6086656 mmcblk0p4 00082434-04
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
CPU: 0 PID: 1 Comm: swapper/0 Not tainted
3.17.0-rc2-00368-gec0400b-dirty #83
What is going on there? Clearly partition table was parsed and
partitions are available; does the mention of unknown-block(0,0) mean
that kernel failed to parse the command line?
I replaced "root=/dev/mmcblk0p2" with "root=b302" and have a booting
system.
