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").
