Please also enable CONFIG_DEBUG_LIST. Looking at the oops:
18: 4a 8b 8c eb 68 01 00 mov 0x168(%rbx,%r13,8),%rcx # l3 =
cachep->nodelists[node];
1f: 00
20: 48 8b 16 mov (%rsi),%rdx
23: 48 8b 46 08 mov 0x8(%rsi),%rax
27: 48 89 42 08 mov %rax,0x8(%rdx)
2b:* 48 89 10 mov %rdx,(%rax) <-- trapping instruction
2e: 89 e8 mov %ebp,%eax
30: 48 c7 06 00 01 10 00 movq $0x100100,(%rsi)
37: 48 c7 46 08 00 02 20 movq $0x200200,0x8(%rsi)
it seems like list_del() in free_block() explodes because because
->prev ("rax") of slab->list is bogus ("0000000000000cd0").
