Solved with new network card.

Since a couple of month ago my server started to drop the network after around 15-20 days uptime. The server works like a charm while it is up, and is no big issue when im at home, since a restart solves the problem for another 15-20 days. Still it is a frustrating issue.. I have googled the problem and havent found a good solution, i know the network controller is the onboard sky2 and that might be the problem. I have 2 ports and have tried both, bonded and not bonded. I have also tried to see if there is something else that can cause the problem, i did a reconfigure of the network, and changed a couple of devices (switch + router), but the problem still exist. I havent bought a new network card (yet) because i'm not 100% sure thats the problem. Here is the log when the network problem occurs (diagnostics file attached aswell): Jan 12 07:57:59 Unraid kernel: br0: port 2(vnet0) entered blocking state Jan 12 07:57:59 Unraid kernel: br0: port 2(vnet0) entered forwarding state Jan 12 09:13:56 Unraid kernel: DMAR: DRHD: handling fault status reg 2 Jan 12 09:13:56 Unraid kernel: DMAR: [DMA Read] Request device [07:00.0] PASID ffffffff fault addr f718f000 [fault reason 06] PTE Read access is not set Jan 12 09:13:56 Unraid kernel: sky2 0000:07:00.0: error interrupt status=0x80000000 Jan 12 09:13:56 Unraid kernel: sky2 0000:07:00.0: PCI hardware error (0x2010) Jan 12 09:14:01 Unraid kernel: ------------[ cut here ]------------ Jan 12 09:14:01 Unraid kernel: NETDEV WATCHDOG: eth0 (sky2): transmit queue 0 timed out Jan 12 09:14:01 Unraid kernel: WARNING: CPU: 7 PID: 6342 at net/sched/sch_generic.c:442 dev_watchdog+0xcf/0x12b Jan 12 09:14:01 Unraid kernel: Modules linked in: macvlan nvidia_uvm(PO) xt_CHECKSUM ipt_REJECT nf_reject_ipv4 ip6table_mangle ip6table_nat iptable_mangle nf_tables vhost_net tun vhost vhost_iotlb tap veth xt_nat xt_tcpudp xt_conntrack nf_conntrack_netlink nfnetlink xt_addrtype br_netfilter xfs md_mod nvidia_drm(PO) nvidia_modeset(PO) drm_kms_helper syscopyarea sysfillrect sysimgblt fb_sys_fops nvidia(PO) drm backlight agpgart hwmon_vid iptable_nat xt_MASQUERADE nf_nat nf_conntrack nf_defrag_ipv6 nf_defrag_ipv4 wireguard curve25519_x86_64 libcurve25519_generic libchacha20poly1305 chacha_x86_64 poly1305_x86_64 ip6_udp_tunnel udp_tunnel libblake2s blake2s_x86_64 libblake2s_generic libchacha ip6table_filter ip6_tables iptable_filter ip_tables x_tables sky2 intel_powerclamp coretemp mxm_wmi kvm_intel kvm crc32c_intel intel_cstate intel_uncore mpt3sas ahci libahci i2c_i801 i7core_edac i2c_smbus i2c_core raid_class input_leds i5500_temp wmi led_class asus_atk0110 scsi_transport_sas button acpi_cpufreq Jan 12 09:14:01 Unraid kernel: [last unloaded: sky2] Jan 12 09:14:01 Unraid kernel: CPU: 7 PID: 6342 Comm: mono Tainted: P W IO 5.10.28-Unraid #1 Jan 12 09:14:01 Unraid kernel: Hardware name: System manufacturer System Product Name/P6X58D PREMIUM, BIOS 1501 05/10/2011 Jan 12 09:14:01 Unraid kernel: RIP: 0010:dev_watchdog+0xcf/0x12b Jan 12 09:14:01 Unraid kernel: Code: 79 b7 00 00 75 38 48 89 ef c6 05 63 79 b7 00 01 e8 79 dd fc ff 44 89 e1 48 89 ee 48 c7 c7 ef 7f de 81 48 89 c2 e8 50 16 10 00 <0f> 0b eb 10 41 ff c4 48 05 40 01 00 00 41 39 f4 75 9d eb 16 48 8b Jan 12 09:14:01 Unraid kernel: RSP: 0018:ffffc90000228ed8 EFLAGS: 00010286 Jan 12 09:14:01 Unraid kernel: RAX: 0000000000000000 RBX: ffff88810143e438 RCX: 0000000000000027 Jan 12 09:14:01 Unraid kernel: RDX: 00000000ffffefff RSI: 0000000000000001 RDI: ffff888a17bd8920 Jan 12 09:14:01 Unraid kernel: RBP: ffff88810143e000 R08: 0000000000000000 R09: 00000000ffffefff Jan 12 09:14:01 Unraid kernel: R10: ffffc90000228d08 R11: ffffc90000228d00 R12: 0000000000000000 Jan 12 09:14:01 Unraid kernel: R13: ffffc90000228f10 R14: ffffc90000228f10 R15: ffffffff820060c8 Jan 12 09:14:01 Unraid kernel: FS: 00001458058fe700(0000) GS:ffff888a17bc0000(0000) knlGS:0000000000000000 Jan 12 09:14:01 Unraid kernel: CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 Jan 12 09:14:01 Unraid kernel: CR2: 000001755284f000 CR3: 00000001283be000 CR4: 00000000000026e0 Jan 12 09:14:01 Unraid kernel: Call Trace: Jan 12 09:14:01 Unraid kernel: <IRQ> Jan 12 09:14:01 Unraid kernel: call_timer_fn.isra.0+0x12/0x6f Jan 12 09:14:01 Unraid kernel: ?
