The problem is that the qib structure embedded in the qeth_irq structure needs an alignment of 256 but kmalloc only guarantees an alignment of 8. When using SLAB debugging the alignment of qeth_irq is not sufficient for the embedded qib structure which causes all users of qdio (qeth and zfcp) to stop working. Allocate qeth_irq structure with __get_free_page. That wastes a small amount of memory (~2500 bytes) per online adapter.
