hi,

kernel panic on mainline(commit: 48d212a2eecaca) with a large system, which
has 120Gb RAM & 8 numa nodes:

[    3.423472] Kernel panic - not syncing: Attempted to kill the idle task!

whole console log is here: 
http://www.sanweiying.org/download/debug_kernel/kernel_panic_48d212a2eecaca
and config file is 
http://www.sanweiying.org/download/debug_kernel/config_48d212a2eecaca

and I have tested different branches, more details is available in 
https://lkml.org/lkml/2012/6/6/704
here I do a simple summary:
  a), mainline, 
v3.4:                                                         no such panic
  b), mainline, v3.5-rc1(commit: 48d212a2eecaca),     yes
  c), Andrea's tree, autonuma15                                     yes
  d), tip/master(commit:b2f5ce55c4e68370)                no such panic

let me know if you need any info.

Thanks,
Zhouping
