Greetings all,
Running CentOS 6.5 x86_64 2.6.32-431.5.1.el6.x86_64. (already booting with the irqpoll option in grub)
Every few months I lose network connectivity and have to restart the server:
in /var/log/messages:
" Mar 7 18:54:21 backup03 kernel: irq 68: nobody cared (try booting with the "irqpoll" option) Mar 7 18:54:21 backup03 kernel: Pid: 0, comm: swapper Not tainted 2.6.32-431.1.2.0.1.el6.x86_64 #1 Mar 7 18:54:21 backup03 kernel: Call Trace: Mar 7 18:54:21 backup03 kernel: <IRQ> [<ffffffff810e8ffb>] ? __report_bad_irq+0x2b/0xa0 Mar 7 18:54:21 backup03 kernel: [<ffffffff810e91fc>] ? note_interrupt+0x18c/0x1d0 Mar 7 18:54:21 backup03 kernel: [<ffffffff810e9845>] ? handle_edge_irq+0xf5/0x180 Mar 7 18:54:21 backup03 kernel: [<ffffffff8100faf9>] ? handle_irq+0x49/0xa0 Mar 7 18:54:21 backup03 kernel: [<ffffffff81530fec>] ? do_IRQ+0x6c/0xf0 Mar 7 18:54:21 backup03 kernel: [<ffffffff8100b9d3>] ? ret_from_intr+0x0/0x11 Mar 7 18:54:21 backup03 kernel: [<ffffffff8107a893>] ? __do_softirq+0x73/0x1e0 Mar 7 18:54:21 backup03 kernel: [<ffffffff810ac9da>] ? tick_program_event+0x2a/0x30 Mar 7 18:54:21 backup03 kernel: [<ffffffff8100c30c>] ? call_softirq+0x1c/0x30 Mar 7 18:54:21 backup03 kernel: [<ffffffff8100fa75>] ? do_softirq+0x65/0xa0 Mar 7 18:54:21 backup03 kernel: [<ffffffff8107a795>] ? irq_exit+0x85/0x90 Mar 7 18:54:21 backup03 kernel: [<ffffffff815310ba>] ? smp_apic_timer_interrupt+0x4a/0x60 Mar 7 18:54:21 backup03 kernel: [<ffffffff8100bb93>] ? apic_timer_interrupt+0x13/0x20 Mar 7 18:54:21 backup03 kernel: <EOI> [<ffffffff812e09ce>] ? intel_idle+0xde/0x170 Mar 7 18:54:21 backup03 kernel: [<ffffffff812e09b1>] ? intel_idle+0xc1/0x170 Mar 7 18:54:21 backup03 kernel: [<ffffffff81426707>] ? cpuidle_idle_call+0xa7/0x140 Mar 7 18:54:21 backup03 kernel: [<ffffffff81009fc6>] ? cpu_idle+0xb6/0x110 Mar 7 18:54:21 backup03 kernel: [<ffffffff81520e2c>] ? start_secondary+0x2ac/0x2ef Mar 7 18:54:21 backup03 kernel: handlers: Mar 7 18:54:21 backup03 kernel: [<ffffffffa015f260>] (e1000_msix_other+0x0/0x1f0 [e1000e]) Mar 7 18:54:21 backup03 kernel: Disabling IRQ #68 "

I'm already booting with irqpoll set in grub:
kernel /vmlinuz-2.6.32-431.5.1.el6.x86_64 ro root=UUID=b535f362-3152-4cc1-a9f2-b86f44331510 nomodeset rd_NO_LUKS KEYBOARDTYPE=pc KEYTABLE=us LANG=en_US.UTF-8 rd_NO_MD quiet SYSFONT=latarcyrheb-sun16 rhgb crashkernel=auto rd_NO_LVM rd_NO_DM irqpoll
Anyone have any ideas or suggestions? Not sure what else I can do here.
Thanks in advance!
