So does kernel 3.13 address all of these stability issues I've been having with the 7260 wireless NIC? The communication between driver and firmware seems to frequently deadlock. When I reinitialize the following stack trace spits out: [12152.263634] WARNING: CPU: 2 PID: 199 at drivers/net/wireless/iwlwifi/mvm/tx.c:684 iwl_mvm_rx_tx_cmd+0x58c/0x5e0 [iwlmvm]() [12152.263636] Modules linked in: snd_hda_codec_hdmi joydev arc4 snd_hda_codec_realtek x86_pkg_temp_thermal coretemp nls_cp437 kvm_intel iTCO_wdt vfat fat iTCO_vendor_support kvm crct10dif_pclmul crct10dif_common crc32_pclmul crc32c_intel ghash_clmulni_intel aesni_intel aes_x86_64 lrw gf128mul iwlmvm glue_helper ablk_helper cryptd microcode mac80211 btusb evdev psmouse serio_raw bluetooth pcspkr iwlwifi rtsx_pci_ms memstick cfg80211 i915 thermal wmi intel_agp thinkpad_acpi battery snd_hda_intel nvram tpm_tis ac rfkill tpm tpm_bios intel_gtt drm_kms_helper snd_hda_codec snd_hwdep e1000e snd_pcm video drm snd_page_alloc mei_me snd_timer mei snd button i2c_i801 ptp soundcore i2c_algo_bit shpchp pps_core i2c_core processor lpc_ich nfs lockd sunrpc fscache ext4 crc16 mbcache jbd2 sd_mod rtsx_pci_sdmmc mmc_core [12152.263699] ahci libahci libata scsi_mod ehci_pci ehci_hcd rtsx_pci xhci_hcd usbcore usb_common [12152.263709] CPU: 2 PID: 199 Comm: irq/61-iwlwifi Tainted: G W 3.12.7-2-ARCH #1 [12152.263711] Hardware name: LENOVO 20ALCTO1WW/20ALCTO1WW, BIOS GIET66WW (2.16 ) 12/02/2013 [12152.263713] 0000000000000009 ffff8800d55e9c38 ffffffff814ec113 0000000000000000 [12152.263725] ffff8800d55e9c70 ffffffff81061b8d ffff8800d433c618 ffff8800d41317d0 [12152.263728] ffff8800d433c668 ffff8800d433c678 ffff8800d41317d8 ffff8800d55e9c80 [12152.263731] Call Trace: [12152.263738] [<ffffffff814ec113>] dump_stack+0x54/0x8d [12152.263743] [<ffffffff81061b8d>] warn_slowpath_common+0x7d/0xa0 [12152.263746] [<ffffffff81061c6a>] warn_slowpath_null+0x1a/0x20 [12152.263752] [<ffffffffa09f9b0c>] iwl_mvm_rx_tx_cmd+0x58c/0x5e0 [iwlmvm] [12152.263756] [<ffffffffa09f49fd>] iwl_mvm_rx_dispatch+0x13d/0x160 [iwlmvm] [12152.263762] [<ffffffffa07dba08>] iwl_pcie_irq_handler+0xff8/0x12e0 [iwlwifi] [12152.263767] [<ffffffff810b69d0>] ? irq_finalize_oneshot.part.29+0xd0/0xd0 [12152.263770] [<ffffffff810b69f0>] irq_thread_fn+0x20/0x50 [12152.263773] [<ffffffff810b69d0>] ? irq_finalize_oneshot.part.29+0xd0/0xd0 [12152.263776] [<ffffffff810b6d2f>] irq_thread+0x11f/0x150 [12152.263780] [<ffffffff810b6b50>] ? wake_threads_waitq+0x50/0x50 [12152.263783] [<ffffffff810b6c10>] ? irq_thread_dtor+0xc0/0xc0 [12152.263787] [<ffffffff81083f60>] kthread+0xc0/0xd0 [12152.263791] [<ffffffff81083ea0>] ? kthread_create_on_node+0x120/0x120 [12152.263794] [<ffffffff814fab7c>] ret_from_fork+0x7c/0xb0 [12152.263798] [<ffffffff81083ea0>] ? kthread_create_on_node+0x120/0x120 [12152.263800] ---[ end trace d95aa1d60ba2d57e ]--- It looks like in Linus' post to LKML with the shortlog there happen to be a lot of fixes to iwlwifi for talking to the firmware in addition to some interrupt related fixes. I'd like some confirmation from active devs, though. The firmware version bump for the 7260 for 3.13 seems to be a good indicator but I don't know for sure. Should I continue holding out or should I order a new PCI-E atheros adapter? I'm currently using kernel 3.12.7. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
