Not sure if this is a network issue, since the problem is in apic.c, but since it was all network functions prior, I figured something kicked it off. I found an apparent patch for find_busiest_group, but it didn't make it into the mainline in six months, so I assume it's either wrong, broke, or the implementation is whacked. stack segment: 0000 [#1] SMP CPU: 0 EIP: 0060:[] Not tainted VLI EFLAGS: 00010246 (2.6.11-rc1-bk8) EIP is at find_busiest_group+0xc9/0x310 eax: c8000980 ebx: c8000980 ecx: ded227ff edx: c89c3680 esi: dd89d000 edi: c0314b40 ebp: 00000002 esp: c04bddbc ds: 007b es: 007b ss: 0068 Process swapper (pid: 0, threadinfo=c04bc000 task=c0408b60) Stack: c0314b69 c8000980 c038800a ded22800 c047e5e0 c04bde20 c0542650 80000000 c02f0512 dd89d000 c0314b40 00000002 c04bde1c c79e4810 00000002 00000002 c0314b40 c02f0818 ded22800 dd89d000 c04bde20 c0314b40 80000000 00000000 Call Trace: [] ip_forward_finish+0x29/0x50 [] ip_sabotage_out+0x10a/0x180 [] nf_iterate+0x72/0xb0 [] ip_forward_finish+0x0/0x50 [] ip_forward_finish+0x0/0x50 [] nf_hook_slow+0x68/0xf0 [] ip_forward_finish+0x0/0x50 [] ip_forward+0x1bc/0x280 [] ip_forward_finish+0x0/0x50 [] ip_rcv_finish+0x1f8/0x270 [] br_nf_pre_routing_finish+0x0/0x290 [] br_nf_pre_routing+0x24b/0x3f0 [] br_nf_pre_routing_finish+0x0/0x290 [] ip_sabotage_in+0x1c/0x30 [] nf_iterate+0x72/0xb0 [] ip_rcv_finish+0x0/0x270 [] ip_rcv_finish+0x0/0x270 [] nf_hook_slow+0x68/0xf0 [] ip_rcv_finish+0x0/0x270 [] ip_rcv+0x3ec/0x4b0 [] ip_rcv_finish+0x0/0x270 [] br_handle_frame_finish+0x0/0xf0 [] netif_receive_skb+0x20d/0x2b0 [] process_backlog+0x86/0x120 [] net_rx_action+0x7f/0x110 [] __do_softirq+0xb6/0xd0 [] do_softirq+0x2d/0x30 [] do_IRQ+0x1e/0x30 [] common_interrupt+0x1a/0x20 [] default_idle+0x23/0x30 [] cpu_idle+0x5f/0x70 [] start_kernel+0x13f/0x160 [] unknown_bootoption+0x0/0x1c0 Code: 26 00 8b 45 c4 85 c0 0f 84 35 02 00 00 8b 3c 8d 20 30 51 c0 b8 c0 e0 50 c0 01 f8 8b 50 04 8b 40 08 c1 e2 07 39 c2 0f 43 c2 ff 45 41 01 c6 ba 08 00 00 00 89 d8 e8 27 51 0e 00 83 f8 09 ba 08 <0>Kernel panic - not syncing: Fatal exception in interrupt David
