Comment(by Quozl):

 Looks like it is mwifiex.

 On the XO-4 B1 SKU292 the mwifiex_sdio module was blacklisted, verified
 not present using lsmod, and the slab corruption did not occur.

 On the XO-4 C2 SKU306 the btmrvl_sdio module was blacklisted, verified not
 present using lsmod, and the slab corruption continued to occur.  Serial
 console log at http://dev.laptop.org/~quozl/z/1UnKV5.txt

 On the XO-4 C1 SKU296 after blacklisting mwifiex_sdio and btmrvl_sdio an
 occasional hang during boot has increased from two in ten to nine in ten.
 Still gathering data.
