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:

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!
