Hi all, I think maybe this is a regression bug, because i'm not met the same issue in 2.6.32 kernel. So change regression to "YES". -- Thanks, Qiao I detected the same problem after the upgrade from 3.10.0-229.1.2.el7.x86_64 (latest CentOS 7 kernel) to Linux 4.0.0 (4.0.0-1.el7.elrepo.x86_64) [ 14.674581] ------------[ cut here ]------------ [ 14.674591] WARNING: CPU: 0 PID: 836 at drivers/dma/ioat/dca.c:698 ioat3_dca_init+0x1ac/0x1c0 [ioatdma]() [ 14.674593] ioatdma 0000:00:04.0: APICID_TAG_MAP set incorrectly by BIOS, disabling DCA [ 14.674594] Modules linked in: mfd_core(E+) snd(E+) soundcore(E) ioatdma(E+) shpchp(E) acpi_power_meter(E) nfsd(E) auth_rpcgss(E) nfs_acl(E) lockd(E) grace(E) uinput(E) sunrpc(E) dm_multipath(E) xfs(E) libcrc32c(E) sd_mod(E) mxm_wmi(E) igb(E) ptp(E) ahci(E) pps_core(E) libahci(E) dca(E) i2c_algo_bit(E) libata(E) wmi(E) dm_mirror(E) dm_region_hash(E) dm_log(E) dm_mod(E) [ 14.674628] CPU: 0 PID: 836 Comm: systemd-udevd Tainted: G E 4.0.0-1.el7.elrepo.x86_64 #1 [ 14.674630] Hardware name: Supermicro X10DAx/X10DAX, BIOS 1.00 12/10/2014 [ 14.674631] 0000000000000000 00000000f94f2e02 ffff8810373a3988 ffffffff816ab3dc [ 14.674635] 0000000000000000 ffff8810373a39e0 ffff8810373a39c8 ffffffff8107858a [ 14.674638] 0000000000000000 ffff8820381b5f30 ffff882038236000 ffff880d50f59300 [ 14.674642] Call Trace: [ 14.674650] [<ffffffff816ab3dc>] dump_stack+0x45/0x57 [ 14.674656] [<ffffffff8107858a>] warn_slowpath_common+0x8a/0xc0 [ 14.674661] [<ffffffff8107867e>] warn_slowpath_fmt_taint+0x4e/0x70 [ 14.674666] [<ffffffffa009f7f1>] ? alloc_dca_provider+0x21/0x40 [dca] [ 14.674671] [<ffffffffa009f7f1>] ? alloc_dca_provider+0x21/0x40 [dca] [ 14.674679] [<ffffffffa02e205c>] ioat3_dca_init+0x1ac/0x1c0 [ioatdma] [ 14.674685] [<ffffffffa02e1416>] ioat3_dma_probe+0x3a6/0x420 [ioatdma] [ 14.674693] [<ffffffffa02d918e>] ioat_pci_probe+0x11e/0x1b0 [ioatdma] [ 14.674699] [<ffffffff8135c965>] local_pci_probe+0x45/0xa0 [ 14.674709] [<ffffffff8135dbf5>] ? pci_match_device+0xe5/0x110 [ 14.674716] [<ffffffff8135dd59>] pci_device_probe+0xf9/0x150 [ 14.674726] [<ffffffff8145b3c0>] driver_probe_device+0x90/0x3c0 [ 14.674730] [<ffffffff8145b7cb>] __driver_attach+0x9b/0xa0 [ 14.674734] [<ffffffff8145b730>] ? __device_attach+0x40/0x40 [ 14.674737] [<ffffffff81459243>] bus_for_each_dev+0x73/0xc0 [ 14.674742] [<ffffffff8145ae4e>] driver_attach+0x1e/0x20 [ 14.674745] [<ffffffff8145aa10>] bus_add_driver+0x180/0x250 [ 14.674748] [<ffffffffa039f000>] ? 0xffffffffa039f000 [ 14.674752] [<ffffffff8145bfd4>] driver_register+0x64/0xf0 [ 14.674756] [<ffffffff8135c2bc>] __pci_register_driver+0x4c/0x50 [ 14.674762] [<ffffffffa039f08a>] ioat_init_module+0x8a/0x1000 [ioatdma] [ 14.674771] [<ffffffff81002144>] do_one_initcall+0xd4/0x210 [ 14.674777] [<ffffffff811d4f39>] ? kmem_cache_alloc_trace+0x199/0x220 [ 14.674783] [<ffffffff816a6dcd>] ? do_init_module+0x28/0x1cc [ 14.674787] [<ffffffff816a6e06>] do_init_module+0x61/0x1cc [ 14.674793] [<ffffffff810fdc49>] load_module+0x1219/0x1940 [ 14.674797] [<ffffffff810f9600>] ? store_uevent+0x70/0x70 [ 14.674801] [<ffffffff810fa549>] ? copy_module_from_fd.isra.48+0x129/0x180 [ 14.674807] [<ffffffff810fe596>] SyS_finit_module+0xa6/0xd0 [ 14.674818] [<ffffffff816b2a89>] system_call_fastpath+0x12/0x17 [ 14.674822] ---[ end trace bb9f66ec925949db ]--- additional information: NVidia driver kernel module from NVidia is used and manual patched to compile with Linux 4.0.
