This one is tracked here: https://bugzilla.kernel.org/show_bug.cgi?id=98591 > This problem has existed on all kernel versions I've tried, although I > haven't tried a 4.0 kernel yet. > This is a tricky HW timing issues which (as you can imagine) we can't reproduce internally. You seem to have a LENOVO whereas the submitted of the bugzilla above has some other OEM. We are currently checking with our System people (who know the HW) how we should address that. > --Andy > > [70699.024982] iwlwifi 0000:03:00.0: RF_KILL bit toggled to enable radio. > [70699.036852] iwlwifi 0000:03:00.0: L1 Enabled - LTR Disabled > [70699.095638] iwlwifi 0000:03:00.0: L1 Enabled - LTR Disabled > [70699.188983] ------------[ cut here ]------------ > [70699.189002] WARNING: CPU: 1 PID: 910 at > drivers/net/wireless/iwlwifi/pcie/trans.c:1361 > iwl_trans_pcie_grab_nic_access+0x128/0x140 [iwlwifi]() > [70699.189004] Timeout waiting for hardware access (CSR_GP_CNTRL 0x080003dc) > [70699.189005] Modules linked in: nfnetlink_queue nfnetlink_log > nfnetlink rfcomm vfat fat uas usb_storage fuse ccm xt_CHECKSUM > iptable_mangle bridge stp llc tun ip6t_REJECT nf_reject_ipv6 > nf_conntrack_ipv6 nf_defrag_ipv6 ipt_MASQUERADE nf_nat_masquerade_ipv4 > iptable_nat nf_conntrack_ipv4 nf_defrag_ipv4 xt_conntrack nf_nat_ipv4 > ip6table_filter nf_nat bnep nf_conntrack ip6_tables arc4 intel_rapl > iosf_mbi iTCO_wdt x86_pkg_temp_thermal iTCO_vendor_support coretemp > kvm_intel btusb snd_hda_codec_hdmi kvm iwlmvm bluetooth > snd_hda_codec_conexant snd_hda_codec_generic mac80211 snd_hda_intel > snd_hda_controller snd_hda_codec iwlwifi snd_hwdep snd_seq > snd_seq_device snd_pcm joydev cfg80211 serio_raw sdhci_pci i2c_i801 > sdhci thinkpad_acpi mmc_core snd_timer tpm_tis wmi mei_me rfkill tpm > mei snd lpc_ich shpchp soundcore > [70699.189040] mfd_core nfsd auth_rpcgss nfs_acl lockd grace sunrpc > binfmt_misc dm_crypt i915 crct10dif_pclmul crc32_pclmul crc32c_intel > e1000e i2c_algo_bit drm_kms_helper ghash_clmulni_intel drm ptp > pps_core video > [70699.189054] CPU: 1 PID: 910 Comm: NetworkManager Not tainted > 3.19.7-200.fc21.x86_64 #1 > [70699.189055] Hardware name: LENOVO 4286CTO/4286CTO, BIOS 8DET69WW > (1.39 ) 07/18/2013 > [70699.189057] 0000000000000000 00000000e8df4a59 ffff8800d66972e8 > ffffffff8176f1f7 > [70699.189060] 0000000000000000 ffff8800d6697340 ffff8800d6697328 > ffffffff8109bc1a > [70699.189062] ffff8800d6697380 ffff8800d6698000 0000000000000000 > ffff8800d669bc30 > [70699.189065] Call Trace: > [70699.189072] [<ffffffff8176f1f7>] dump_stack+0x45/0x57 > [70699.189077] [<ffffffff8109bc1a>] warn_slowpath_common+0x8a/0xc0 > [70699.189080] [<ffffffff8109bca5>] warn_slowpath_fmt+0x55/0x70 > [70699.189085] [<ffffffff813a3248>] ? delay_tsc+0x48/0x80 > [70699.189092] [<ffffffffa046da78>] > iwl_trans_pcie_grab_nic_access+0x128/0x140 [iwlwifi] > [70699.189098] [<ffffffffa04604ce>] iwl_set_bits_mask_prph+0x3e/0xa0 > [iwlwifi] > [70699.189103] [<ffffffffa046cce3>] iwl_pcie_set_pwr+0x43/0x70 [iwlwifi] > [70699.189108] [<ffffffffa046edec>] > iwl_trans_pcie_start_fw+0xec/0x710 [iwlwifi] > [70699.189115] [<ffffffffa0639266>] > iwl_mvm_load_ucode_wait_alive+0x106/0x300 [iwlmvm] > [70699.189119] [<ffffffffa0639000>] ? 0xffffffffa0639000 > [70699.189125] [<ffffffffa06399bc>] iwl_mvm_up+0x6c/0x460 [iwlmvm] > [70699.189131] [<ffffffffa063e5cc>] __iwl_mvm_mac_start+0x2c/0x370 [iwlmvm] > [70699.189135] [<ffffffff816dca28>] ? ip_mc_up+0x48/0x80 > [70699.189140] [<ffffffffa063e938>] iwl_mvm_mac_start+0x28/0x40 [iwlmvm] > [70699.189155] [<ffffffffa04ed1c1>] ieee80211_do_open+0x311/0xda0 [mac80211] > [70699.189167] [<ffffffffa04edcc1>] ieee80211_open+0x71/0x80 [mac80211] > [70699.189171] [<ffffffff8165e03e>] __dev_open+0xce/0x150 > [70699.189175] [<ffffffff8165e381>] __dev_change_flags+0xa1/0x170 > [70699.189178] [<ffffffff8165e479>] dev_change_flags+0x29/0x70 > [70699.189181] [<ffffffff813b1491>] ? list_del+0x11/0x40 > [70699.189185] [<ffffffff8166e0ef>] do_setlink+0x39f/0xb70 > [70699.189189] [<ffffffff811bc230>] ? zone_statistics+0x80/0xa0 > [70699.189192] [<ffffffff811bc230>] ? zone_statistics+0x80/0xa0 > [70699.189195] [<ffffffff813c1252>] ? nla_parse+0x32/0x120 > [70699.189198] [<ffffffff8166effd>] rtnl_newlink+0x5fd/0x7a0 > [70699.189203] [<ffffffff8131f2c8>] ? security_capable+0x18/0x20 > [70699.189206] [<ffffffff810a413d>] ? ns_capable+0x2d/0x60 > [70699.189209] [<ffffffff8166b011>] rtnetlink_rcv_msg+0xa1/0x260 > [70699.189212] [<ffffffff8168b07d>] ? __netlink_lookup+0x4d/0x70 > [70699.189215] [<ffffffff8166af70>] ? rtnetlink_rcv+0x40/0x40 > [70699.189217] [<ffffffff8168f0e9>] netlink_rcv_skb+0xb9/0xe0 > [70699.189220] [<ffffffff8166af5c>] rtnetlink_rcv+0x2c/0x40 > [70699.189222] [<ffffffff8168e7fd>] netlink_unicast+0x12d/0x1c0 > [70699.189225] [<ffffffff8168ebb0>] netlink_sendmsg+0x320/0x680 > [70699.189227] [<ffffffff81322712>] ? sock_has_perm+0x72/0x90 > [70699.189231] [<ffffffff8163f47c>] do_sock_sendmsg+0x9c/0x110 > [70699.189235] [<ffffffff8163edec>] ? copy_msghdr_from_user+0x15c/0x210 > [70699.189238] [<ffffffff8163fac0>] ___sys_sendmsg+0x330/0x340 > [70699.189241] [<ffffffff811ca250>] ? tlb_flush_mmu_free+0x40/0x60 > [70699.189244] [<ffffffff811caf8c>] ? tlb_finish_mmu+0x1c/0x50 > [70699.189247] [<ffffffff81238bb5>] ? __fget_light+0x25/0x70 > [70699.189250] [<ffffffff8163f740>] ?
