I'll try bisecting further inside that section (unless you tell me not to), but it may take some time. The exact point during the startup sequence when the crash occurred and the amount of BUG messages produced varied somewhat during these tests. The common denominator, and my criterion for the good/bad decisions during the bisect, was the crash (panic blink) just before completion of the system startup. Sometimes there weren't any BUG messages in the log (or perhaps they just didn't make it to the disk.) Sometimes I just had a couple of the "sleeping function called from invalid context at mm/slab.c:3054" ones but no "Eeek! page_mapcount(page) went negative!" one before them. However, whenever the "Eeek!" did appear it announced "getcfg-interfac" as the current process and was followed by a few of the "mm/slab.c:3054" ones.
