Hello Thomas,

Good catch! The problem was sg_init_table was missing for small buffer
size. When CONFIG_DEBUG_SG is off, you won't hit this, but your test has
DEBUG_SG on so SG_MAGIC check failed. You can turn DEBUG_SG off to avoid
this.

I thought you should hit the same problem before since I didn't remember
sg_init_table was used for small message size.

I will submit a patch for fix this issue soon.

Thanks
Shirley
