That must have been it :) I'd prefer this version to Yinghai's if it works, since it will avoid putting everything on node 0 (the whole point of the patch in the first place). Thanks,

My T60p doesn't crash with it so I'm assuming it's some bootstrap issue with an initscript reading `local_cpus' before the per-cpu nodemasks are allocated. CONFIG_DEBUG_PER_CPU_MAPS might be able to diagnose the issue. -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

The code is a: 49 63 fc movslq %r12d,%rdi d: 0f 49 d3 cmovns %ebx,%edx 10: c1 f8 1f sar $0x1f,%eax 13: 4c 01 ff add %r15,%rdi 16: c1 e8 1a shr $0x1a,%eax 19: c1 fa 06 sar $0x6,%edx 1c: 41 c1 e8 02 shr $0x2,%r8d 20: 8d 0c 03 lea (%rbx,%rax,1),%ecx 23: 48 63 d2 movslq %edx,%rdx 26: 83 e1 3f and $0x3f,%ecx 29: 29 c1 sub %eax,%ecx 2b:* 49 8b 44 d5 00 mov 0x0(%r13,%rdx,8),%rax <-- trapping instruction 30: 48 c7 c2 8c 37 16 82 mov $0xffffffff8216378c,%rdx 37: 48 d3 e8 shr %cl,%rax 3a: 89 f1 mov %esi,%ecx 3c: 44 89 f6 mov %r14d,%esi and the obvious reason seems to be that 'maskp' is NULL (that faulting thing is the code for "val = (maskp[word] >> bit) & chunkmask;" with the actual fault being the access of "maskp[word]". Now, the caller does mask = cpumask_of_pcibus(to_pci_dev(dev)->bus); and then uses cpumask_scnprintf() that is just a wrapper that does bitmap_scnprintf(buf, len, cpumask_bits(srcp), nr_cpumask_bits); So clearly we have "cpumask_of_pcibus()" being NULL (cpumask_bits() would not change it). I assume this is the NUMA case? The non-NUMA case has just static inline const struct cpumask *cpumask_of_node(int node) { return cpu_online_mask; } so I don't think you can ever get NULL (if we have a NULL cpu_online_mask we have bigger problems). [ Side note: looking closer, I think our headers are buggy, and I _know_ they are confusing. The above inline declaration of cpumask_of_node() seems to be then later overridden in <asm-generic/topology.h> by a #define! And if I read that right, that will also override the debugging versions that we declared if CONFIG_DEBUG_PER_CPU_MAPS is on. Ingo? Rusty? Am I missing something? That said, those overrides should only happen for non-NUMA ] The NUMA version of 'cpumask_of_node()' has all the debug code for show it's not returning NULL, but only when CONFIG_DEBUG_PER_CPU_MAPS is enabled. Otherwise it all seems to boil down to (through cpumask_of_pcibus and __pcibus_to_node): node_to_cpumask_map[bus->sysdata->node] and it can fail either because "node" isn't initialized, or node_to_cpumask_map[] isn't. Probably 'node' is still -1, and it gets the NULL by going off the array into la-la-land.
