Hi Andrew,

Following Kernel panic is raised while booting up with 2.6.23-rc3-mm1 
kernel.

============================================================
Inode-cache hash table entries: 65536 (order: 6, 262144 bytes)

Memory: 32480436k/33554432k available (2146k kernel code, 278984k 
reserved, 1203k data, 216k init, 31842304k highmem)
virtual kernel memory layout:

Kernel panic - not syncing: Can't create pid_1 cachep

To add to the panic, it begin called by the __init pidmap_init
of kernel/pid.c:641
        init_pid_ns.pid_cachep = create_pid_cachep(1);
        if (init_pid_ns.pid_cachep == NULL)
                panic("Can't create pid_1 cachep\n");

Thanks & Regards

Andrew after setting CONFIG_SLUB=n and CONFIG_SLAB, it hits
a kernel Bug, and attaching the config file.

static void *____cache_alloc_node(struct kmem_cache *cachep, gfp_t flags,
                                int nodeid)
{
        struct list_head *entry;
        struct slab *slabp;
        struct kmem_list3 *l3;
        void *obj;
        int x;

        l3 = cachep->nodelists[nodeid];
        BUG_ON(!l3);

I _looks_ like an ordering problem, but slab is all set up by then.

Strange.
