Hi Dave, The hardware platform is 2 x AR9390 manufactured by Senao on an apu2c4.
01:00.0 "Network controller" "Qualcomm Atheros" "AR93xx Wireless Network Adapter" -r01 "Qualcomm Atheros" "Device 0205" 05:00.0 "Network controller" "Qualcomm Atheros" "AR93xx Wireless Network Adapter" -r01 "Qualcomm Atheros" "Device 3114" I tried booting adding nocpu or maxcpus=0 to grub but this will not boot. Would I have to use a build without SMP support? Do you have another suggested method for achieving this? I am using a build with Kernel 4.9.8 now and this crashes with kernel panics such as: LEDE Reboot SNAPSHOT r3386-0799de6 / LuCI Master (git-17.041.67116-1834eff) [ 85.116532] IPv6: ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready [ 85.123276] br-lan: port 3(wlan0) entered blocking state [ 85.128841] br-lan: port 3(wlan0) entered forwarding state [ 338.599214] BUG: unable to handle kernel paging request at 0000000000015968 [ 338.606286] IP: [<ffffffff81085b57>] native_queued_spin_lock_slowpath+0x120/0x16c [ 338.613870] PGD 118888067 [ 338.616419] PUD 11888a067 PMD 0 [ 338.619725] [ 338.621271] Oops: 0002 [#1] SMP [ 338.624445] Modules linked in: ath9k ath9k_common pppoe ppp_async ath9k_hw ath pppox ppp_generic nf_conntrack_ ipv6 mac80211 iptable_nat ipt_REJECT ipt_MASQUERADE cfg80211 xt_time xt_tcpudp xt_state xt_nat xt_multiport xt_ma rk xt_mac xt_limit xt_conntrack xt_comment xt_TCPMSS xt_REDIRECT xt_LOG xt_CT slhc r8169 nf_reject_ipv4 nf_nat_re direct nf_nat_masquerade_ipv4 nf_conntrack_ipv4 nf_nat_ipv4 nf_nat nf_log_ipv4 nf_defrag_ipv6 nf_defrag_ipv4 nf_c onntrack_rtcache nf_conntrack iptable_mangle iptable_filter ip_tables e1000e crc_ccitt compat i2c_dev ip6t_REJECT nf_reject_ipv6 nf_log_ipv6 nf_log_common ip6table_mangle ip6table_filter ip6_tables x_tables igb i2c_algo_bit i2 c_core e1000 button_hotplug ptp pps_core mii [ 338.689162] CPU: 1 PID: 0 Comm: swapper/1 Not tainted 4.9.8 #0 [ 338.695044] Hardware name: PC Engines apu2/apu2, BIOS 6f1e98a-dirty 05/15/2016 [ 338.702346] task: ffff88011a0a7080 task.stack: ffffc90000060000 [ 338.708294] RIP: 0010:[<ffffffff81085b57>] [<ffffffff81085b57>] native_queued_spin_lock_slowpath+0x120/0x16c [ 338.718298] RSP: 0018:ffff88011ec83d88 EFLAGS: 00010202 [ 338.723650] RAX: 000000000000065c RBX: ffff880118fd9858 RCX: 0000000000015968 [ 338.730818] RDX: ffff88011ec95940 RSI: 0000000000080000 RDI: ffff880118fcb4d0 [ 338.737994] RBP: ffff88011ec83e70 R08: 0000000000000001 R09: 0000000000000000 [ 338.745160] R10: ffffc900015ef920 R11: ffff880119b8da00 R12: ffff880118745820 [ 338.752326] R13: ffff88011ec83ec0 R14: ffff880119975500 R15: ffff880118fc9c20 [ 338.759488] FS: 0000000000000000(0000) GS:ffff88011ec80000(0000) knlGS:0000000000000000 [ 338.767637] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 338.773411] CR2: 0000000000015968 CR3: 0000000118a82000 CR4: 00000000000406e0 [ 338.780578] Stack: [ 338.782618] ffffffff8143a9af ffffffffa0286c95 0000000000000000 0000000000000000 [ 338.790155] 0000000000000000 0000000000000000 0000000000000400 ffff88011ec83ea0 [ 338.797703] ffffffff00000000 ffff880118fcb4b0 0000000000000000 ffff880118fc8de0 [ 338.805235] Call Trace: [ 338.807718] <IRQ> [ 338.809670] [<ffffffff8143a9af>] ? _raw_spin_lock_bh+0x21/0x24 [ 338.815662] [<ffffffffa0286c95>] ? ath_tx_aggr_wakeup+0x1ed/0xafa [ath9k] [ 338.822583] [<ffffffff8107f8f9>] ? load_balance+0x14e/0x6f8 [ 338.828297] [<ffffffffa0282c94>] ? __ath9k_flush+0x3a8/0x5fb [ath9k] [ 338.834787] [<ffffffffa0287ffe>] ? ath_tx_edma_tasklet+0x2d0/0x2f8 [ath9k] [ 338.841796] [<ffffffffa0281c73>] ? ath9k_tasklet+0x178/0x1d1 [ath9k] [ 338.848290] [<ffffffff81060c1a>] ? tasklet_action+0x9f/0xa8 [ 338.853985] [<ffffffff81060e44>] ? __do_softirq+0xb8/0x1a1 [ 338.859599] [<ffffffff810610bc>] ? irq_exit+0x4f/0x5b [ 338.864777] [<ffffffff810143ab>] ? do_IRQ+0xa4/0xba [ 338.869774] [<ffffffff8143b53f>] ? common_interrupt+0x7f/0x7f [ 338.875643] <EOI> [ 338.877593] [<ffffffff8132d26c>] ? cpuidle_enter_state+0x134/0x189 [ 338.883921] [<ffffffff8132d225>] ? cpuidle_enter_state+0xed/0x189 [ 338.890130] [<ffffffff81084b96>] ? cpu_startup_entry+0x156/0x1c9 [ 338.896262] [<ffffffff810266d5>] ? start_secondary+0x12b/0x12e [ 338.902217] Code: e8 10 66 87 47 02 c1 e0 10 74 67 48 89 c1 c1 e8 12 48 c1 e9 0c ff c8 83 e1 30 48 98 48 81 c1 40 59 01 00 48 03 0c c5 60 82 77 81 <48> 89 11 8b 42 08 85 c0 75 04 f3 90 eb f5 48 8b 0a 48 85 c9 74 [ 338.922815] RIP [<ffffffff81085b57>] native_queued_spin_lock_slowpath+0x120/0x16c [ 338.930458] RSP <ffff88011ec83d88> [ 338.933972] CR2: 0000000000015968 [ 338.937322] ---[ end trace 6525cac670e9dcbc ]--- [ 338.941968] Kernel panic - not syncing: Fatal exception in interrupt [ 338.948380] Kernel Offset: disabled [ 338.951898] Rebooting in 3 seconds..[ 341.956062] ACPI MEMORY or I/O RESET_REG.
