I did some research on that error and it seems that other user have similar errors as well. Take a look at Re: Uninterruptible sleep during Edison SPI . At the moment I’m not sure how to resolve this but keep an eye on the post; we are working to post a reply there.
To add more space to /dev/root you can check How to boot Edison from an SD card (Linux) and follow the steps.
Hi, Alvarado, Thank you very much for your concern and advices.
As to add more space to /dev/root. I don't want to boot Edison from external storage.
After I flush my edison. The /dev/root is already 89% occupied. But there are a lot of spaces in /home dir. Can I
rearrange the partition of the directory and How?

I noticed you marked my previous comments as correct; do you still need assistance with this thread?
Yes, I think what I want is to decrease the space of /home dir and increase the space of /dev/root dir rather than use an external storage. But I fear that this is infeasible.
Thanks, Alvarado. I guess it may work. Since I am in China, I tried to build yocto ealier but it failed, because some packages can't be fetched.
