Hi all.
I have two servers

CentOS release 5.7 (Final)
Both have two external gigabit network cards (installed Planet with
Realtek r8169 chipset).

I have random network connectivity problems only reboot helps for some
time, then the problem returns.
I've added irqpoll option to kernel line in grub.conf but it hasn't helped.
I've checked options in bios but haven't found anything interesting.
Any clues what to do next?
Best regards,
Rafal Radecki.
