TC3600刀片在AMD6272+平台CPU+soft+Lockup+解决方案

1曙光TC3600AMD6272平台CPUsoftLockup处理方法问题说明：在中山大学TC3600AMD6272平台联调测试过程中，节点在测试过程中频繁出现kernelsoftlockup错误（详细错误参见附录1），影响集群正常使用。处理方式：修改系统启动选项，关闭acpi、apic部分功能，节点稳定性提高。如下所示，其中红色部分为启动选项添加部分。root(hd0,0)kernel/vmlinuz-2.6.32-220.23.1.el6.x86_64roroot=UUID=5f8041c3-b34e-4baa-9304-808d387c8fa8rd_NO_LUKSrd_NO_LVMLANG=en_US.UTF-8rd_NO_MDquietSYSFONT=latarcyrheb-sun16rhgbcrashkernel=128MKEYBOARDTYPE=pcKEYTABLE=usrd_NO_DMacpi=htnoapic附录1：BUG:softlockup-CPU#6stuckfor67s![IMB-MPI1:17787][c3]Moduleslinkedin:ip6table_filterip6_tablesebtable_natebtablesipt_MASQUERADEiptable_natnf_natnf_conntrack_ipv4nf_defrag_ipv4xt_statenf_conntrackipt_REJECTCpuSpy(P)(U)xt_CHECKSUMiptable_mangleknem(U)bridgeautofs4sunrpc8021qgarpstpllciptable_filterip_tablesrdma_ucm(U)rdma_cm(U)iw_cm(U)ib_addr(U)ib_ipoib(U)ib_cm(U)ib_sa(U)ipv6ib_uverbs(U)ib_umad(U)iw_nes(U)libcrc32cmlx4_ib(U)mlx4_en(U)mlx4_core(U)ib_mthca(U)ib_mad(U)ib_core(U)vhost_netmacvtapmacvlantunkvm_amdkvmsgigbdcamicrocodeamd64_edac_modedac_coreedac_mce_amdi2c_piix4i2c_coreshpchpext4mbcachejbd2sd_modcrc_t10difmpt2sasscsi_transport_sasraid_classata_genericpata_acpipata_atiixpahcidm_mirro2rdm_region_hashdm_logdm_mod[lastunloaded:scsi_wait_scan][c3]CPU6[c3]Moduleslinkedin:ip6table_filterip6_tablesebtable_natebtablesipt_MASQUERADEiptable_natnf_natnf_conntrack_ipv4nf_defrag_ipv4xt_statenf_conntrackipt_REJECTCpuSpy(P)(U)xt_CHECKSUMiptable_mangleknem(U)bridgeautofs4sunrpc8021qgarpstpllciptable_filterip_tablesrdma_ucm(U)rdma_cm(U)iw_cm(U)ib_addr(U)ib_ipoib(U)ib_cm(U)ib_sa(U)ipv6ib_uverbs(U)ib_umad(U)iw_nes(U)libcrc32cmlx4_ib(U)mlx4_en(U)mlx4_core(U)ib_mthca(U)ib_mad(U)ib_core(U)vhost_netmacvtapmacvlantunkvm_amdkvmsgigbdcamicrocodeamd64_edac_modedac_coreedac_mce_amdi2c_piix4i2c_coreshpchpext4mbcachejbd2sd_modcrc_t10difmpt2sasscsi_transport_sasraid_classata_genericpata_acpipata_atiixpahcidm_mirrordm_region_hashdm_logdm_mod[lastunloaded:scsi_wait_scan][c3][c3]Pid:17787,comm:IMB-MPI1Tainted:P----------------2.6.32-220.13.1.el6.x86_64#1MICRO-STARINTERNATIONALCO.,LTDMS-91F2/MS-91F2[c3]RIP:0010:[ffffffff814ef83e][ffffffff814ef83e]_spin_lock+0x1e/0x30[c3]RSP:0018:ffff8809732459f8EFLAGS:00000293[c3]RAX:0000000000000129RBX:ffff8809732459f8RCX:0000000000000000[c3]RDX:0000000000000127RSI:ffff880973245a78RDI:ffffffff81fab308[c3]RBP:ffffffff8100bc0eR08:ffffffff81c002c0R09:0000000000000000[c3]R10:0000000000000010R11:0000000000001000R12:0000000000000000[c3]R13:0000000000001000R14:ffffffff8113bd57R15:ffff880973245a28[c3]FS:00002b26791b4480(0000)GS:ffff8800282c0000(0000)knlGS:0000000000000000[c3]CS:0010DS:0000ES:0000CR0:0000000080050033[c3]CR2:00002b267c31e230CR3:000000015c096000CR4:00000000000406e0[c3]DR0:0000000000000000DR1:0000000000000000DR2:0000000000000000[c3]DR3:0000000000000000DR6:00000000ffff0ff0DR7:0000000000000400[c3]ProcessIMB-MPI1(pid:17787,threadinfoffff880973244000,taskffff880973243540)[c3]Stack:[c3]ffff880973245a58ffffffff81148684ffff88000004c218ffff880973245a38[c3]0ffff880973245a18ffff880973245a18ffff880415c980c000000000000000013[c3]00000000000000030ffff8800fc8c5000ffff880c2e572cb0ffff880c2e572d58[c3]CallTrace:[c3][ffffffff81148684]?__purge_vmap_area_lazy+0x174/0x1e0[c3][ffffffff8114a23d]?vm_unmap_aliases+0x16d/0x180[c3][ffffffff810446be]?change_page_attr_set_clr+0xbe/0x530[c3][ffffffff81073974]?walk_system_ram_range+0x64/0x130[c3][ffffffff81072cf0]?__is_ram+0x0/0x10[c3][ffffffff8104539f]?_set_memory_uc+0x2f/0x40[c3][ffffffff81046502]?reserve_memtype+0x492/0x590[c3][ffffffff810434eb]?ioremap_change_attr+0x2b/0x40[c3][ffffffff81045d56]?kernel_map_sync_memtype+0x86/0xf0[c3][ffffffff8104674d]?reserve_pfn_range+0x14d/0x1e0[c3][ffffffff81046863]?track_pfn_vma_new+0x83/0x90[c3][ffffffff81138554]?remap_pfn_range+0xa4/0x4a0[c3][ffffffff8115f7e2]?kmem_cache_alloc+0x182/0x190[c3][ffffffff81177f58]?alloc_file+0x98/0xe0[c3][ffffffff811baa88]?anon_inode_getfile+0x128/0x200[c3][ffffffffa0234ab3]?mlx4_ib_mmap+0x83/0x100[mlx4_ib][c3][ffffffffa026502c]?ib_uverbs_mmap+0x2c/0x30[ib_uverbs][c3][ffffffff811421c0]?mmap_region+0x400/0x590[c3][ffffffff8114268a]?do_mmap_pgoff+0x33a/0x380[c3][ffffffff81132120]?sys_mmap_pgoff+0x200/0x2d0[c3][ffffffff8117724c]?sys_write+0x7c/0x90[ffffffff81010469]?sys_mmap+0x29/0x30[c3][ffffffff8100b0f2]?system_call_fastpath+0x16/0x1b[c3]Code:000000017405e86279d8ffc9c3554889e50f1f440000b800000100f00fc1070fb7d0c1e81039c2740ef3900fb717ebf5833f0075f4ebdfc9c30f1f4000554889[c3]CallTrace:[c3][ffffffff81148684]?__purge_vmap_area_lazy+0x174/0x1e0[c3][ffffffff8114a23d]?vm_unmap_aliases+0x16d/0x180[c3][ffffffff810446be]?change_page_attr_set_clr+0xbe/0x530[c3][ffffffff81073974]?walk_system_ram_range+0x64/0x130[c3][ffffffff81072cf0]?__is_ram+0x0/0x10[c3][ffffffff8104539f]?_set_memory_uc+0x2f/0x404[c3][ffffffff81046502]?reserve_memtype+0x492/0x590[c3][ffffffff810434eb]?ioremap_change_attr+0x2b/0x40[c3][ffffffff81045d56]?kernel_map_sync_memtype+0x86/0xf0[c3][ffffffff8104674d]?reserve_pfn_range+0x14d/0x1e0[c3][ffffffff8104674d]?rese
