August 11, 201510 yr Community Expert I'm seeing the following trace, which would indicate a kernel bug or more likely flaky hardware. Specifically with the Realtek r8169 NIC. Researching online would suggest bag hardware. ------------[ cut here ]------------ WARNING: CPU: 5 PID: 0 at net/sched/sch_generic.c:303 dev_watchdog+0x194/0x1fa() NETDEV WATCHDOG: eth0 (r8169): transmit queue 0 timed out Modules linked in: xt_CHECKSUM iptable_mangle ipt_REJECT nf_reject_ipv4 ebtable_filter ebtables kvm_amd kvm vhost_net vhost macvtap macvlan tun xt_nat veth ipt_MASQUERADE nf_nat_masquerade_ipv4 iptable_nat nf_conntrack_ipv4 nf_nat_ipv4 iptable_filter ip_tables nf_nat md_mod hid_logitech_hidpp fam15h_power k10temp pata_atiixp hid_logitech_dj r8169 mii e1000 i2c_piix4 ahci mpt2sas libahci raid_class scsi_transport_sas acpi_cpufreq CPU: 5 PID: 0 Comm: swapper/5 Not tainted 4.1.1-unRAID #2 Hardware name: To Be Filled By O.E.M.

Here's a pastebin: http://pastebin.com/urdg9DXa Occassionally it would boot up with no network connectivity despite me logging on via console and seeing an IP address. Board: ASRock 970 Extreme4 Found this: http://lime-technology.com/forum/index.php?topic=12192.0 Which pointed to adding the boot parameter: append initrd=/bzroot pcie_aspm=off but that didn't help. Would appear that I'm stuck here.
