--- Begin Message ---Package: firmware-brcm80211 Version: 20190717-2 Severity: important Dear Maintainer, Recently I installed Debian Buster on a Dell XPS 13 9350 laptop, which contains a BCM4350 rev. 08 wireless card. During the installation process I had to grab one of the unofficial CD images containing the non-free firmware to get that downloaded. My internet has ~10MB/s upload/download speed, and on my other computers the speeds are near this limit and are consistently at that speed. However, usually speeds on this wireless card are abnormally at 100-200kB/s, sometimes as low as 30-50kB/s. Furthermore, it often unpredictably switches between such low speeds and 1MB/s speed (which is acceptable). I first attempted to upgrade the firmware to their absolute latest versions, which did not improve the situation. I also noticed that in the brcmfmac description that there's a file for rev. 5+ card but that brcmfmac is only loading the rev. 4 and below card. I wonder if that might be part of the problem. Anyway, here's some diagnostic information: $ inxi -Fx System: Host: tttt4 Kernel: 4.19.0-5-amd64 x86_64 bits: 64 compiler: gcc v: 8.3.0 Desktop: Cinnamon 3.8.8 Distro: Debian GNU/Linux 10 (buster) Machine: Type: Laptop System: Dell product: XPS 13 9350 v: N/A serial: <root required> Mobo: Dell model: 07TYC2 v: A00 serial: <root required> UEFI: Dell v: 1.10.1 date: 01/22/2019 Battery: ID-1: BAT0 charge: 48.7 Wh condition: 51.5/57.5 Wh (89%) model: SMP DELL JHXPY53 status: Unknown CPU: Topology: Dual Core model: Intel Core i5-6200U bits: 64 type: MT MCP arch: Skylake rev: 3 L2 cache: 3072 KiB flags: lm nx pae sse sse2 sse3 sse4_1 sse4_2 ssse3 vmx bogomips: 19200 Speed: 500 MHz min/max: 400/2800 MHz Core speeds (MHz): 1: 500 2: 500 3: 500 4: 500 Graphics: Device-1: Intel HD Graphics 520 vendor: Dell Skylake GT2 driver: i915 v: kernel bus ID: 00:02.0 Display: x11 server: X.Org 1.20.4 driver: modesetting unloaded: fbdev,vesa resolution: 3200x1800~60Hz OpenGL: renderer: Mesa DRI Intel HD Graphics 520 (Skylake GT2) v: 4.5 Mesa 18.3.6 direct render: Yes Audio: Device-1: Intel Sunrise Point-LP HD Audio vendor: Dell driver: snd_hda_intel v: kernel bus ID: 00:1f.3 Sound Server: ALSA v: k4.19.0-5-amd64 Network: Device-1: Broadcom Limited BCM4350 802.11ac Wireless Network Adapter vendor: Dell driver: brcmfmac v: kernel port: f040 bus ID: 3a:00.0 IF: wlp58s0 state: up mac: 30:52:cb:81:ef:1d Drives: Local Storage: total: 238.47 GiB used: 15.24 GiB (6.4%) ID-1: /dev/nvme0n1 vendor: Samsung model: PM951 NVMe 256GB size: 238.47 GiB Partition: ID-1: / size: 225.49 GiB used: 14.94 GiB (6.6%) fs: ext4 dev: /dev/nvme0n1p2 ID-2: swap-1 size: 7.87 GiB used: 294.7 MiB (3.7%) fs: swap dev: /dev/nvme0n1p3 Sensors: System Temperatures: cpu: 39.0 C mobo: 27.8 C Fan Speeds (RPM): N/A Info: Processes: 240 Uptime: 11h 18m Memory: 7.66 GiB used: 3.03 GiB (39.5%) Init: systemd runlevel: 5 Compilers: gcc: 8.3.0 clang: 7.0.1-8 Shell: bash v: 5.0.3 inxi: 3.0.32 $ sudo dmesg | grep brcm [ 4.511409] usbcore: registered new interface driver brcmfmac [ 4.511475] brcmfmac 0000:3a:00.0: enabling device (0000 -> 0002) [ 4.636428] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac4350-pcie for chip BCM4350/8 [ 4.641489] brcmfmac 0000:3a:00.0: firmware: direct-loading firmware brcm/brcmfmac4350-pcie.bin [ 4.641508] brcmfmac 0000:3a:00.0: firmware: failed to load brcm/brcmfmac4350-pcie.txt (-2) [ 4.641576] brcmfmac 0000:3a:00.0: Direct firmware load for brcm/brcmfmac4350-pcie.txt failed with error -2 [ 4.981502] bluetooth hci0: firmware: failed to load brcm/BCM-0a5c-6412.hcd (-2) [ 4.981532] bluetooth hci0: Direct firmware load for brcm/BCM-0a5c-6412.hcd failed with error -2 [ 4.981534] Bluetooth: hci0: BCM: Patch brcm/BCM-0a5c-6412.hcd not found [ 5.085081] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac4350-pcie for chip BCM4350/8 [ 5.085100] brcmfmac 0000:3a:00.0: firmware: failed to load brcm/brcmfmac4350-pcie.clm_blob (-2) [ 5.085148] brcmfmac: brcmf_c_process_clm_blob: no clm_blob available (err=-2), device may have limited channels available [ 5.085405] brcmfmac: brcmf_c_preinit_dcmds: Firmware: BCM4350/8 wl0: Oct 22 2015 06:16:26 version 7.35.180.119 (r594535) FWID 01-e791c176 [ 5.109605] brcmfmac 0000:3a:00.0 wlp58s0: renamed from wlan0 [ 4577.706990] (NULL device *): firmware: direct-loading firmware brcm/brcmfmac4350-pcie.bin [ 4579.525336] WARNING: CPU: 2 PID: 221 at drivers/net/wireless/broadcom/brcm80211/brcmfmac/pno.c:77 brcmf_pno_remove_request+0xac/0xd0 [brcmfmac] [ 4579.525336] Modules linked in: rfcomm fuse squashfs zstd_decompress xxhash cmac loop bnep snd_hda_codec_hdmi joydev intel_rapl binfmt_misc btusb btrtl btbcm btintel bluetooth nls_ascii nls_cp437 vfat fat x86_pkg_temp_thermal drbg intel_powerclamp coretemp dell_laptop kvm_intel ansi_cprng snd_soc_skl ecdh_generic kvm snd_soc_skl_ipc snd_soc_sst_ipc snd_soc_sst_dsp dell_wmi dell_smbios dcdbas wmi_bmof snd_hda_ext_core dell_wmi_descriptor irqbypass snd_soc_acpi_intel_match crct10dif_pclmul crc32_pclmul snd_soc_acpi snd_hda_codec_realtek brcmfmac ghash_clmulni_intel serio_raw intel_cstate snd_hda_codec_generic intel_uncore snd_soc_core brcmutil intel_rapl_perf snd_compress cfg80211 snd_hda_intel rtsx_pci_ms snd_hda_codec efi_pstore memstick hid_multitouch snd_hda_core efivars rfkill snd_hwdep snd_pcm [ 4579.525400] RIP: 0010:brcmf_pno_remove_request+0xac/0xd0 [brcmfmac] [ 4579.525414] brcmf_pno_stop_sched_scan+0x22/0x50 [brcmfmac] [ 4579.525438] brcmf_cfg80211_sched_scan_stop+0x28/0x60 [brcmfmac] [ 4579.525443] brcmf_cfg80211_suspend+0x303/0x340 [brcmfmac] [ 4580.829563] brcmfmac: brcmf_fil_cmd_data: bus is down. we have nothing to do.
