You have been subscribed to a public bug: Whenever switching from high to low, or low to high CPU loads I encounter the attached lockup. This happens at least twice daily when the server is left alone, more often when it actually does anything.
The CPU# changes with each crash, but seems to always be for 22s. ul 25 08:01:59 necronomicon kernel: [32989.183560] ------------[ cut here ]------------ Jul 25 08:01:59 necronomicon kernel: [32989.183569] WARNING: CPU: 0 PID: 0 at /build/linux-Fsa3B1/linux-4.10.0/net/sched/sch_generic.c:316 dev_watchdog+0x22c/0x230 Jul 25 08:01:59 necronomicon kernel: [32989.183571] NETDEV WATCHDOG: enp37s0 (r8169): transmit queue 0 timed out Jul 25 08:01:59 necronomicon kernel: [32989.183572] Modules linked in: binfmt_misc nls_iso8859_1 joydev input_leds snd_hda_codec_hdmi snd_hda_codec_realtek eeepc_wmi snd_hda_codec_generic asus_wmi snd_hda_intel snd_hda_codec snd_hda_core snd_hwdep snd_pcm snd_timer snd soundcore sparse_keymap ccp edac_mce_amd edac_core shpchp i2c_piix4 kvm irqbypass i2c_designware_platform i2c_designware_core 8250_dw mac_hid ib_iser rdma_cm iw_cm ib_cm ib_core configfs iscsi_tcp libiscsi_tcp libiscsi scsi_transport_iscsi ip_tables x_tables autofs4 btrfs raid10 raid456 async_raid6_recov async_memcpy async_pq async_xor async_tx xor raid6_pq libcrc32c raid1 raid0 multipath linear hid_generic usbhid hid nouveau crct10dif_pclmul crc32_pclmul ghash_clmulni_intel pcbc mxm_wmi video i2c_algo_bit ttm drm_kms_helper aesni_intel syscopyarea aes_x86_64 sysfillrect Jul 25 08:01:59 necronomicon kernel: [32989.183610] crypto_simd sysimgblt glue_helper fb_sys_fops cryptd drm r8169 mii ahci libahci wmi gpio_amdpt fjes gpio_generic Jul 25 08:01:59 necronomicon kernel: [32989.183619] CPU: 0 PID: 0 Comm: swapper/0 Tainted: G L 4.10.0-28-generic #32-Ubuntu Jul 25 08:01:59 necronomicon kernel: [32989.183620] Hardware name: System manufacturer System Product Name/PRIME B350M-A, BIOS 0805 06/20/2017 Jul 25 08:01:59 necronomicon kernel: [32989.183621] Call Trace: Jul 25 08:01:59 necronomicon kernel: [32989.183623] <IRQ> Jul 25 08:01:59 necronomicon kernel: [32989.183627] dump_stack+0x63/0x81 Jul 25 08:01:59 necronomicon kernel: [32989.183629] __warn+0xcb/0xf0 Jul 25 08:01:59 necronomicon kernel: [32989.183631] warn_slowpath_fmt+0x5f/0x80 Jul 25 08:01:59 necronomicon kernel: [32989.183634] dev_watchdog+0x22c/0x230 Jul 25 08:01:59 necronomicon kernel: [32989.183637] ?
