No, looks like someone is feeding a bad pointer to slab. The debug check is relatively new and in previous kernels the problem would might have gone unnoticed causing silent corruption of the slab.

Please use the Oops in its original format (from dmesg, etc). Ignore any references in this or other docs to "decoding the Oops" or "running it through ksymoops". If you post an Oops from 2.6 that has been run through ksymoops, people will just tell you to repost it." So, can you please repost the original oops? Also, please enable CONFIG_DEBUG_SLAB and try to reproduce. Thanks.
