Looks like sysfs / driver tree corruption. i2c-0/ contains entries
which normally live in /sys/devices, and some don't even have file
attributes.

Please check if older kernels have the same problem and check that you
use reliable memory.

If you can reproduce the problem, please check the kernel logs for
any relevant message. A kernel with some debugging options enabled
might be good too.

Anyone, that's not a sensors-detect issue.
