SD card, e2fsck

The kernel message is the usual kernel message in this cases,
something along the lines of "booting from an unchecked filesystem,
run e2fsck to correct errors, or something similar. The same message
that would appear in a big computer in the same case.

I can't shutdown only by pressing the poweroff button. I usually
shutdown via halt, but some times the battery runs out before I
remember to shutdown properly, and the next time I have this problem..
I should add a cron script to check for battery capacity and halt when
at 5 or 10.

I don't have fn-keys running, I'm running Debian and I think this was
in OpenWRT.

Kernel log is as usual except for the e2fsck part. When it arrives to
the FPU emulator, then No device for DAI jz4740-i2s and then it hangs
just between this message and the usual next which is asoc jz codec
<-> jz4740-i2s. This means it hangs just before loading /etc/modules
(where I have this second module).

Also, just after e2fscking the system, I usually find some memory
problems, but this is more odd (happened twice, when loading this last
module it finishes with some kind of out of memory error). I'll try to
keep a camera around and take a picture when it happens again.
