I can't reproduce any of these. I modified pseries_defconfig to enable DEBUG_SLAB and it still works for me on my POWER5 here % grep SLAB .config CONFIG_SLAB=y CONFIG_SLABINFO=y CONFIG_DEBUG_SLAB=y # CONFIG_DEBUG_SLAB_LEAK is not set I also can't reproduce with DEBUG_PAGEALLOC enabeled either. > It also fails to boot with SLUB and SLUB_DEBUG enabled, even with > SLUB_DEBUG_ON disabled. pseries_defconfig uses this configuration and boots for me. % grep SLUB .config CONFIG_SLUB_DEBUG=y CONFIG_SLUB=y # CONFIG_SLUB_DEBUG_ON is not set # CONFIG_SLUB_STATS is not set > Ben has access to my system, and will look at it in a few days. Can you please try pseries_defconfig? Mikey _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
