booting in a loop & "General error mounting filesystems.ss"

[stefan]

Hello,

I have finally been able to hook my board's serial connection up with my laptop, so I can inspect the (failing) boot sequence.
Here is a particularly interesting sequence of the output stream:

-----

EXT4-fs (mmcblk0p2): warning: maximal mount count reached, running e2fsck is recommended
EXT4-fs (mmcblk0p2): mounted filesystem with ordered data mode. Opts: (null)
VFS: Mounted root (ext4 filesystem) on device 179:2.
Freeing init memory: 172K
General error mounting filesystems.ss (815) terminated with status 1
A maintenance shell will now be started.
CONTROL-D will terminate this shell and reboot the system.
Inconsistency detected by ld.so: dl-lookup.c: 876: _dl_setup_hash: Assertion `(bitmask_nwords & (bitmask_nwords - 1)) == 0' failed!
EXT4-fs (mmcblk0p2): re-mounted. Opts: (null)nated with status 127
��33�3737�3s������~���n����������~���������;

U-Boot 2012.10-00003-g792c31c (Jan 03 2014 - 12:24:08)

-----

The first thing to note is that, despite the note about a "maintenance shell", the board really reboots immediately (and thus I never get a chance to interfer, and the fs maximum mount count is reached etc.)

I also don't quite understand what the precise error is that triggers the boot process to abort in the first place. Is it the error just above, about "General error mounting filesystems.ss ..." ?
Any idea what I could do about it ? In fact, is there anything I can do (once I mount the filesystem directly from my laptop) to fix the boot process so it will give me the promised maintenance shell ?
Also, what is this error about the ld.so inconsistency detected by ld.so ?

Any help would be greatly appreciated,

What SD card are you using? (brand, model, capacity...)

Try these command on a Ubuntu PC and post the outputs.

Set the SD card to your Ubuntu PC, then

sudo fdisk -l

It's a sandisk 16 GB disk. (fdisk -l reports:

The rootfs filesystem was indeed corrupted beyond repair, so I reinstalled it. Now booting works fine.
Thanks for your help !
