The fault occurred because when CONFIG_SLUB_DEBUG was set, many of the memory allocations for wireless buffers were increased from O(0) to O(1) causing memory fragmentation, and eventually there were no remaining O(1) fragments. This problem is unlikely to affect most users as none of the distos turn on the above debug option. This bug should be marked "closed with patch".
