I'm experiencing very slow speed when I download large files over the air. This doesn't really slow stuff down for web surfing, but when I download large file speed is about 1MB/sec. This started to happen after I installed new version of compat wireless somewhere in the middle of March. Before this I had speed up to 5MB/sec in same environment an dI was running compat-wireless from January. I do not often download large files over the air from another locally connected machine (by wire) so problem was unnoticed for some time and now I cannot really provide exact version when problem started, I'll try to figure this out, though. So problem appears on dell laptop with intel 5300 card running 3.2.9 kernel with some compat wireless from early march. I've tried to install 'vanilla' 3.3 kernel from ubuntu repository and run into exact same problem. I have an ath9k based AP with recent openwrt. Also, after some time downloading at that low speed connection drops completely and I get this in logs: ------------------------------- Mar 29 22:12:19 xxx kernel: [220407.141631] ------------[ cut here ]------------ Mar 29 22:12:19 xxx kernel: [220407.141674] WARNING: at /home/xxx/projects/wireless/compat-wireless/drivers/net/wireless/iwlwifi/iwl-trans-pcie-tx.c:894 iwl_tx_cmd_complete+0x341/0x380 [iwlwifi]() Mar 29 22:12:19 xxx kernel: [220407.141682] Hardware name: MM061 Mar 29 22:12:19 xxx kernel: [220407.141690] wrong command queue 7 (should be 4), sequence 0x2723 readp=7 writep=7 Mar 29 22:12:19 xxx kernel: [220407.141694] Modules linked in: ftdi_sio usbserial binfmt_misc ip6table_filter ip6_tables ipt_MASQUERADE iptable_nat nf_nat nf_conntrack_ipv4 nf_defrag_ipv4 xt_state nf_conntrack ipt_REJECT xt_CHECKSUM iptable_mangle xt_tcpudp iptable_filter ip_tables x_tables bridge stp kvm_intel kvm parport_pc ppdev arc4 iwlwifi(O) mac80211(O) joydev dell_laptop dcdbas snd_hda_codec_idt pcmcia snd_hda_intel snd_hda_codec snd_hwdep snd_pcm snd_seq_midi r852 sm_common nand nand_ids mtd nand_bch bch cfg80211(O) snd_rawmidi snd_seq_midi_event psmouse r592 nand_ecc memstick pcmcia_core snd_seq serio_raw compat(O) snd_timer snd_seq_device lp dm_multipath parport snd dell_wmi sparse_keymap soundcore snd_page_alloc mac_hid btrfs zlib_deflate libcrc32c radeon ttm drm_kms_helper drm firewire_ohci firewire_core video sdhci_pci sdhci wmi ssb crc_itu_t i2c_algo_bit Mar 29 22:12:19 xxx kernel: [220407.141864] Pid: 0, comm: swapper/0 Tainted: G O 3.2.9-030209-generic-pae #201202292059 Mar 29 22:12:19 xxx kernel: [220407.141869] Call Trace: Mar 29 22:12:19 xxx kernel: [220407.141884] [] warn_slowpath_common+0x72/0xa0 Mar 29 22:12:19 xxx kernel: [220407.141911] [] ? iwl_tx_cmd_complete+0x341/0x380 [iwlwifi] Mar 29 22:12:19 xxx kernel: [220407.141937] [] ? iwl_tx_cmd_complete+0x341/0x380 [iwlwifi] Mar 29 22:12:19 xxx kernel: [220407.141946] [] warn_slowpath_fmt+0x33/0x40 Mar 29 22:12:19 xxx kernel: [220407.141971] [] iwl_tx_cmd_complete+0x341/0x380 [iwlwifi] Mar 29 22:12:19 xxx kernel: [220407.141997] [] ? iwl_rx_dispatch+0xce/0xf0 [iwlwifi] Mar 29 22:12:19 xxx kernel: [220407.142023] [] iwl_irq_tasklet+0x447/0xd50 [iwlwifi] Mar 29 22:12:19 xxx kernel: [220407.142035] [] tasklet_action+0xa9/0xe0 Mar 29 22:12:19 xxx kernel: [220407.142043] [] __do_softirq+0x9e/0x1b0 Mar 29 22:12:19 xxx kernel: [220407.142052] [] ? nmi_stack_correct+0x2f/0x34 Mar 29 22:12:19 xxx kernel: [220407.142061] [] ? irq_enter+0x70/0x70 Mar 29 22:12:19 xxx kernel: [220407.142069] [] ? irq_enter+0x70/0x70 Mar 29 22:12:19 xxx kernel: [220407.142073] [] ? irq_exit+0x9d/0xc0 Mar 29 22:12:19 xxx kernel: [220407.142087] [] ? do_IRQ+0x4b/0xc0 Mar 29 22:12:19 xxx kernel: [220407.142095] [] ? sched_clock_local+0xb2/0x190 Mar 29 22:12:19 xxx kernel: [220407.142104] [] ? common_interrupt+0x30/0x38 Mar 29 22:12:19 xxx kernel: [220407.142112] [] ? sys_olduname+0xcb/0x1b0 Mar 29 22:12:19 xxx kernel: [220407.142122] [] ? acpi_idle_enter_simple+0xef/0x12a Mar 29 22:12:19 xxx kernel: [220407.142134] [] ? cpuidle_idle_call+0xab/0x1d0 Mar 29 22:12:19 xxx kernel: [220407.142143] [] ? cpu_idle+0xa4/0xe0 Mar 29 22:12:19 xxx kernel: [220407.142152] [] ? rest_init+0x5d/0x70 Mar 29 22:12:19 xxx kernel: [220407.142162] [] ? start_kernel+0x35e/0x364 Mar 29 22:12:19 xxx kernel: [220407.142170] [] ? kernel_init+0x14a/0x14a Mar 29 22:12:19 xxx kernel: [220407.142178] [] ? i386_start_kernel+0xb3/0xbb Mar 29 22:12:19 xxx kernel: [220407.142184] ---[ end trace faabf7cf620ccbbe ]--- Mar 29 22:12:19 xxx kernel: [220407.142192] iwl data: 00000000: 00 00 55 55 0e 52 23 27 c4 01 d9 08 28 da e4 d8 ..UU.R#'....(...
