Hi there,

I'm playing around with the latest snapshots on my IGEPv2 and I'm

seeing a recurring message posted to the console while using it:

[ 1561.340942] INFO: task kworker/0:0:1030 blocked for more than 120
    seconds.
[ 1561.350860] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs"
    disables this message.
[ 1681.356597] INFO: task kworker/0:0:1030 blocked for more than 120
    seconds.
[ 1681.367187] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs"
    disables this message.

root@linaro:~# uname -a

I'd like to find out what that task is meant to be doing and why it is getting blocked. I haven't been able to notice anything negative in my use of the system (downloading and installing packages, editing files, running cpuburn and stress).

Same happens from time to time on PandaBoard.
