Package: r8169 Kernel: 5.10.0-8 (amd64)
System: Debian 11 (bullseye) libc: 2.31 Hi. I state that this problem is present from kernel 5.4 and still has not been fixed ... suddenly, the ethernet stops working and this error appears (in dmesg): [ 12.063469] NETDEV WATCHDOG: eth0 (r8169): transmit queue 0 timed out [ 12.063509] WARNING: CPU: 3 PID: 0 at net/sched/sch_generic.c:467 dev_watchdog+0x24d/0x260 [ 12.063520] Modules linked in: joydev hid_logitech_hidpp uvcvideo videobuf2_vmalloc hid_gener ic videobuf2_memops videobuf2_v4l2 videobuf2_common snd_usb_audio videodev snd_usbmidi_lib snd_r awmidi usbhid snd_seq_device mc hid intel_rapl_msr intel_rapl_common rfkill snd_hda_codec_realte k snd_hda_codec_generic ledtrig_audio snd_hda_codec_hdmi snd_hda_intel snd_intel_dspcfg x86_pkg_ temp_thermal soundwire_intel intel_powerclamp soundwire_generic_allocation snd_soc_core coretemp snd_compress soundwire_cadence kvm_intel snd_hda_codec snd_hda_core nvidia_drm(POE) mei_hdcp kvm snd_hwdep soundwire_bus irqbypass drm_kms_helper snd_pcm rapl intel_cstate snd_timer iTCO_wdt m ei_me snd intel_pmc_bxt iTCO_vendor_support intel_uncore mei watchdog soundcore ee1004 sg intel_ wmi_thunderbolt pcspkr cec nvidia_modeset(POE) evdev acpi_pad intel_pmc_core nvidia(POE) corefre qk(OE) parport_pc ppdev drm lp parport fuse configfs ip_tables x_tables autofs4 ext4 crc16 mbcac he jbd2 crc32c_generic uas usb_storage sd_mod [ 12.063805] t10_pi crc_t10dif crct10dif_generic crct10dif_pclmul crct10dif_common crc32_pclm ul crc32c_intel ahci libahci ghash_clmulni_intel libata xhci_pci scsi_mod xhci_hcd aesni_intel i 2c_i801 i2c_smbus usbcore r8169 libaes crypto_simd realtek mdio_devres cryptd libphy glue_helper usb_common wmi fan video button [ 12.063917] CPU: 3 PID: 0 Comm: swapper/3 Tainted: P OE 5.10.0-8-amd64 #1 Debia n 5.10.46-4 [ 12.063922] Hardware name: Gigabyte Technology Co., Ltd.

I noticed that it happens when I restart the PC a couple of times. Many people have this problem. I can't currently use ethernet! Thanks
