hi,
kernel panic on mainline(commit: 48d212a2eecaca) with a large system, which has 120Gb RAM & 8 numa nodes:
... [cut here] ... [ 3.404017] Call Trace: [ 3.404553] [<ffffffff810afd19>] find_busiest_group+0x39/0x4b0 [ 3.406188] [<ffffffff810b0295>] load_balance+0x105/0xa50 [ 3.407444] [<ffffffff810ce2ed>] ? trace_hardirqs_off+0xd/0x10 [ 3.408695] [<ffffffff810aa1cf>] ? local_clock+0x6f/0x80 [ 3.409789] [<ffffffff810b11b0>] idle_balance+0x130/0x2d0 [ 3.410879] [<ffffffff810b10d0>] ? idle_balance+0x50/0x2d0 [ 3.411996] [<ffffffff8167f340>] __schedule+0x910/0xa00 [ 3.413204] [<ffffffff8167f769>] schedule+0x29/0x70 [ 3.414324] [<ffffffff8102352f>] cpu_idle+0x12f/0x140 [ 3.415433] [<ffffffff81667765>] start_secondary+0x262/0x264 [ 3.416763] Code: 44 8b bd 7c ff ff ff 45 85 ff 0f 85 30 02 00 00 48 8b bd 48 ff ff ff 48 8b 4f 10 4c 8b 45 98 8b 71 04 31 d2 4c 89 c0 48 c1 e0 0a <48> f7 f6 48 8b 75 a0 48 85 f6 48 89 c7 49 89 c1 48 89 45 90 0f [ 3.420335] RIP [<ffffffff810af93b>] update_sd_lb_stats+0x27b/0x620 [ 3.421664] RSP <ffff88041922fb48> [ 3.422473] ---[ end trace 04b848dd1c06d585 ]--- [ 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
