I've the same problem:
I've do apt-get dist-upgrate, then apt-get update.
After a while I want to install vlc. Just type apt-get install vlc and wait.
When I have low disk space message.
I look at /var/log it was 6.4Gb.
Files kern.log and syslog was filled with message.

code not in kernel 3.4.0.

I have also found this issue on a Pandaboard running 3.4.0-1489-omap4,
log messages are the same, CPU maxed out and /var/log/messages is about
6GB now!

I expirince this from time to time with linux-linaro-lt-omap-3.4-3.4.0
kernel which as far as I know is based on linux-ti-omap4:

The bug reproduces on the latest kernel by any sufficiently intensive
inbound network traffic.

Same problem here. Any intense inbound data transfer will trigger it,
but is seems that outbound transfers are good.
